TheSixthInternationalConferenceonImplementationandApplicationof- tomata(CIAA2001) the?rstoneheldinthesouthernhemisphere was heldattheUniversityofPretoriainPretoria,SouthAfrica,on23 25July2001. ThisvolumeofSpringer sLectureNotesinComputerSciencecontainsall thepapers(includingtheinvitedtalkbyGregorv.

Automatatheoryisoneoftheoldestareasincomputerscience. Researchin automatatheoryhasbeenmotivatedbyitsapplicationssinceitsearlystagesof development. Inthe1960sand1970s,automataresearchwasmotivatedheavily byproblemsarisingfromcompilerconstruction,circuitdesign,stringmatching, etc. Inrecentyears,manynewapplicationsofautomatahavebeenfoundin variousareasofcomputerscienceaswellasinotherdisciplines. Examplesofthe newapplicationsincludestatechartsinobject-orientedmodeling,?nitetra- ducersinnaturallanguageprocessing,andnondeterministic?nite-statemodels incommunicationprotocols. Manyofthenewapplicationscannotsimplyutilize theexistingmodelsandalgorithmsinautomatatheorytosolvetheirproblems. Newmodels,ormodi?cationsoftheexistingmodels,areneededtosatisfytheir requirements. Also,thesizesofthetypicalproblemsinmanyofthenewapp- cationsareastronomicallylargerthanthoseusedinthetraditionalapplications.
