CAT, AVIS, CMCS, COCV, DCC, EAAI, FESCA, FRCSS, GT-VMT, LDTA, MBT,
QAPL,SC,SLAP,SPIN,TERMGRAPH,WITSandWRLA),twotutorials,andseven
invited lectures (notincluding those that were specific to the satellite events). We re-
ceivedover550submissionstothefiveconferencesthisyear,givinganoverallaccep-

tions to all the authors who made it to the final programme! I hope that most of the
otherauthorsstillfoundawayofparticipatinginthisexcitingeventandIhopeyouwill
continuesubmitting.
The events that comprise ETAPS address various aspects of the system develop-
ment process, including specification, design, implementation, analysis and improve-
ment. The languages, methodologies and tools which support these activities are all
wellwithin itsscope.Differentblendsof theoryandpracticeare represented,withan
inclination towards theory with a practical motivation on the one hand and soundly
based practice on the other. Many of the issues involved in software design apply to
systems in general, including hardware systems, and the emphasis on software is not
intendedtobeexclusive.
ETAPS is a loose confederationin which each event retains its own identity, with
a separate Program Committee and proceedings. Its format is open-ended, allowing
it to grow and evolve as time goes by. Contributed talks and system demonstrations
areinsynchronizedparallelsessions,withinvitedlecturesinplenarysessions.Twoof

Preface
Thisvolumecollectsthe proceedingsof“FoundationsofSoftware Scienceand Com-
putationStructures,”FOSSACS 2006.FOSSACS is a memberconferenceof ETAPS,
the “European Joint Conferences on Theory and Practice of Software,” dedicated to
foundationalresearchforsoftwarescience.Itinvitessubmissionsontheoriesandmeth-
odstounderpintheanalysis,integration,synthesis,transformation,andverificationof
programsandsoftwaresystems.Topicscoveredusuallyinclude:algebraicmodels;au-
tomata and language theory; behavioral equivalences; categorical models; computa-
tionprocessesoverdiscreteandcontinuousdata;computationstructures;logicsofpro-
grams;modal,spatial,andtemporallogics;modelsofconcurrent,reactive,distributed,
andmobilesystems;modelsofsecurityandtrust;language-basedsecurity;processal-
gebras and calculi; semantics of programming languages; software specification and
refinement;typesystemsandtypetheory.
FOSSACS 2006 consisted of one invited and 28 contributed papers, selected out
of 107 submissions, yielding an acceptance rate of roughly 26%. The quality of the
submitted papers was very high indeed, and several good manuscripts could not be
selected for presentationat the conferenceby the ProgramCommittee.This indicates
thatFOSSACSisbynowanestablishedconferenceontheoreticalcomputerscienceto
whichtheauthorsaresubmittingsomeoftheirbestwork.
Besides the contributed papers, this volume includes an article by Wan Fokkink,
the FOSSACS invited speaker. Wan’s contribution,entitled ‘On Finite Alphabetsand
Infinite Bases II: Completed and Ready Simulation,’ is coauthored with Taolue Chen
and Sumit Nain—two young, up-and-coming researchers—and presents new results
ontheequationaltheoryofsimulation-basedpreorderingrelationsbetweenconcurrent
processes.
