Preface
Waves and wave interactions in plasmas is written in a lucid and system-
atic way to serve as a special book for advanced post graduate students
andresearchersinApplied Mathematics, PlasmaPhysics, Nonlineardiffer-
m
o ential equations, Nonlinear Optics, and other Engineering branches where
c
c.
ntifi nonlinear wave phenomena is studied. The first chapter deals with basic
e plasma with elementary definitions of magnetized and unmagnetized plas-
ci
ds mas, plasma modeling, dusty plasma, and quantum plasma. In Chapter 2,
orl
w we deal with linear and nonlinear waves, solitons and shocks, and other
w.
w wave phenomena.
w
m In Chapter 3, solution of some nonlinear wave equations is discussed
o
d fr by using some standard technique. Chapter 4 starts with elementary
de knowledgeofperturbationandnonperturbationmethods. Severalevolution
a
o
nl equations are obtained in different plasma situations and properties of
w
Do solitons in those environments are discussed. In Chapter 5, Higher-order

correction to those equations and the improvement of the solution is are
discussed. In Chapter 6, evolution equations in nonplanar geometry are
obtained and the wave solution for such equation is also obtained. In
Chapter 7, different type collisions of solitons in a plasma environment
is discussed. The phenomena of soliton turbulence are also discussed as
a consequence of multi soliton interactions. In Chapter 8, the properties
of large amplitude solitary wavesare obtained by using a non perturbative
approach called Sagdeev’s Pseudopotential Approach. Speed and shape of
solitons are also discussed in this chapter. Possiblefuture developments of
research in this area are explained in brief in Chapter 9.
