We have already discovered the basic laws that govern matter and understand all the normal situations. We don’t know how the laws fit together, and what happens under extreme conditions. But I expect we will find a complete unified theory sometime this century. There is no limit to the complexity that we can build using those basic laws. Stephen Hawking, January 2000. We don’t know what we are talking about. Many of us believed that string theory was a very dramatic break with our previous notions of quantum theory. But now we learn that string theory, well, is not that much of a break. The state of physics today is like it was when we were mystified by radioactivity. They were missing something absolutely fundamental. We are missing perhaps something as profound as they were back then. Nobel Laureate David Gross, December 2005. This volume is essentially a compilation of papers presented at the Inter- national Workshop on Mathematics and Physics of Complex and Nonlinear Systems that was held at Indian Institute of Technology Kanpur, March 14 – 26, 2004 on the theme ChaNoXity: The Nonlinear Dynamics of Nature. ChaNoXity — symbolizing Chaos-Nonlinearity-compleXity — is an attempt to understand and interpret the dynamical laws of Nature on a unified and global perspective. The Workshop’s objective was to formalise the concept of chanoxity and to get the diverse body of practitioners of its components to interact intelligently with each other. It was aimed at a focused debate and discussion on the mathematics and physics of chaos, nonlinearity, and complexity in the dynamical evolution of nature. This is expected to induce a process of reeducation and reorientation to supplement the basically linear reductionistapproachofpresentdaysciencethatseekstobreakdownnatural VIII Preface systemstotheirsimpleconstituentswhosepropertiesareexpectedtocombine in a relatively simple manner to yield the complex laws of the whole. There were approximately 40 hours of lectures by 12 speakers; in keeping with its aim of providing an open platform for exposition and discourse on the the- matic topic, each of the 5-6 lectures a day were of 75 minutes duration so as to provide an adequate and meaningful interaction, formal and informal, between the speaker and his audience. The goals of the workshop were to (cid:1) Createanawarenessamongtheparticipants,drawnfromtheresearchand educational institutions in India and abroad, of the role and significance of nonlinearity in its various manifestations and forms. (cid:1) Present an overview of the strong nonlinearity of chaos and complexity in natural systems from the mathematical and physical perspectives. The relevant mathematics were drawn from topology, measure theory, inverse and ill-posed problems, set-valued and nonlinear functional analyses. (cid:1) Exploretheroleofnon-extensivethermodynamicsandstatisticalmechan- ics in open, nonlinear systems. Therewerelivelyandanimateddiscussionsonself-organizationandemer- gence in the attainment of steady-states of open, far-from-equilibrium, com- plex systems, and on the mechanism of how such systems essentially cheat the dictates of the all-pervading Second Law of Thermodynamics1: where lies the source of Schrodinger’s negative entropy that successfully maintains life despite the Second Law? How does Nature defeat itself in this game of the SecondLaw,andwhatmightbethepossibleroleofgravityinthisenterprise? Although it is widely appreciated that gravity — the only force to have suc- cessfully resisted integration in a unified theory — is a major player in the dynamics of life, realization of a satisfactory theory has proved to be diffi- cult, with loop quantum cosmology holding promise in resolving the vexing “big-bang singularity problem”. The distinctive feature of this loop quantiza- tion is that the quantum Wheeler-DeWitt differential equation (that fails to remove the singularity, backward evolution leading back into it), is replaced by a difference equation, the size of the discrete steps determined by an area gap, Riemannian geometry now being quantized with the length, area, vol- ume operators possessing discrete eigenvalues. Discrete difference equations, loops of one-dimensional objects (based on spin-connections rather than on themetricsofstandardGeneralRelativity)consideredintheperiod-doubling 1 The second law of thermodynamics holds, I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell’s equations then so much the worse for Maxwell’s equations. If it is found to be contradicted by observation, well, these experimentalists do bungle things sometimes. But if your theory is found tobeagainstthe secondlawofthermodynamics I cangiveyounohope;there is nothing for it but to collapse in deepest humiliation. A. Eddington, The Nature of the Physical World, Macmillan, New York (1948). Preface IX perspective,theextremenonlinearcurvatureofbig-bangandblackholechaotic spacetimes: do all these point to a radically different paradigm in the chaos- nonlinearity-complexity setting of discrete dynamical systems?2 Thus is it “a quantum foam far removed from any classical spacetime, or is there another large, classical universe” on the “other side of the singularity responsible for a quantumbouncefromanexpandingbranchtoacontractingbranch”?3 Could thispossiblybetheoutcomeoftheinteractionofourclassicalrealworldwitha negativepartneractingastheprovideroftheillusorynegativeentropy,whose attraction manifests on us as the repulsive “quantum bounce” through the agency of gravity? Would the complex structure of “life” and of the universe as we know it exist without the partnership of gravity? NotallthepaperspresentedattheWorkshopappearhere;notableexcep- tions among those who gave three or more lectures are S. Kesavan (Institute of Mathematical Science at Chennai, India) who spoke on Topological Degree and Bifurcation Theory, and M. Z. Nashed (University of Central Florida, USA) whose paper Recovery Problems from Partial or Indirect Information: Perspectives on Inverse and Ill-Posed Problems could not be included due to unavoidable circumstances. The volume contains three papers by Realpe and Ordonez, Majumdar, and Johal that were not presented at the Workshop. A brief overview of the papers appearing follows. Francisco Balibrea (Universidad de Murcia, Spain) provides a compre- hensive review of the complicated dynamics of discrete dynamical systems in a compact metric space using the notions of Li-Yorke and Devaney chaos, sensitive dependence of initial conditions, transitivity, Lyapunov exponents, and the Kolmogorov-Sinai and topological entropies. Sumiyoshi Abe (Uni- versity of Tsukuba, Japan) surveys the fundamental aspects of nonextensive statistical mechanics based on the Tsallis entropy, and demonstrates how the methodofsteepestdescents,thecountingalgorithmandtheevaluationofthe densityofstatescanappropriatelybegeneralizedfordescribingthepower-law distributions. Alberto Robledo (Universidad Nacional Autonoma de Mex- ico, Mexico) gives an account of the dynamics at critical attractors of simple one-dimensional nonlinear maps relevant to the applicability of the Tsallis generalization of canonical statistical mechanics. Continuing in this spirit of non-extensivity, A. G. Bashkirov (R.A.S. Moscow, Russia) considers the RenyientropyasacumulantaverageoftheBoltzmannentropy,andfindsthat the thermodynamic entropy in Renyi thermostatistics increases with system complexity,withtheRenyidistributionbecomingapurepower-lawunderap- propriate conditions. He concludes that “because a power-law distribution is characteristicforself-organizingsystems,theRenyientropycanbeconsidered as a potential that drives the system to a self-organized state”.

John Realpe (Universidad del Valle, Colombia) and Gonzalo Ordonez (Butler University, Indianapo- lis and The University of Texas at Austin, USA) study two points of view on the origin of irreversible processes. While the “chaotic hypothesis” holds that irreversible processes originate in the randomness generated by chaotic dynamics, the approach of the Prigogine school maintains that irreversibility is rooted in Poincare non-integrability associated with resonances. Consider- ing the simple model of Brownian motion of a harmonic oscillator coupled to lattice vibration modes, the authors show that Brownian trajectories re- quire resonance between the particle and the lattice, with chaos playing only a secondary role for random initial conditions. If the initial conditions are not random however, chaos is the dominant player leading to thermalization of the lattice and consequent appearance of Brownian resonance character- istics. R. S. Johal (Lyallpur Khalsa College, India) considers the approach to equilibrium of a system in contact with a heat bath and concludes, in the context of non-extensivity, that differing bath properties yield differing equi- librium distributions of the system. Parthasarathi Majumdar (S.I.N.P., India) reviews black hole thermodynamics for non-experts, underlining the need for considerations beyond classical general relativity. The origin of the microcanonical entropy of isolated, non-radiant, non-rotating black holes is tracedinthisperspectiveintheLoopQuantumGravity formulationofquan- tumspacetime.Russ Marion(ClemsonUniversity,USA)appliescomplexity theorytoorganizationalsciencesandfindsthat“theimplicationsaresosignif- icantthattheysignalaparadigmshiftinthewayweunderstandorganization and leadership”. Complexity theory, in his view, alters our perceptions about the logic of organizational behavior which rediscovers the significant impor- tance of firms’ informal social dynamics that have long been “suppressed or channeled”. He feels that a complexity appraoch to organizations is particu- larly relevant in view of the recent emphasis in industrialized nations toward knowledge-based, rather than production-based, economies. A. Sengupta (I.I.T. Kanpur, India) employs the topological-multifunctional mathematical language and techniques of non-injective illposedness to formulate the notion of chanoxity in describing the specifically nonlinear dynamical evolutionary processesofNature.Non-bijectiveill-posednessisthenaturalmodeofexpres- sion for chanoxity that aims to focus on the nonlinear interactions generating dynamical evolution of real irreversible processes.
