Springer Verification, Induction, Termination Analysis: Festschrift for Christoph Walther on the Occasion of His 60th Birthday: 6463 (Lecture Notes in Computer Science, 6463)

th This Festschrift is dedicated to Christoph Walther on the occasion of his 60 th birthday on August 9 , 2010. It consists of articles by some of his colleagues and former students, who, on this momentous occasion, chose to show their appreciation. Inteachingtheoreticalcomputerscience,Christophhas hadaprofoundin- ence onmany ofhis formerandcurrentstudents,notleastby the introductionof eriFun into the classroom. Outside of his teaching, developing eriFun played a major role in his recent research activities. When the idea for this Festschrift was ?rst presented to us, it quickly - came apparent that Christoph's work in the ?elds of veri?cation, induction and termination analysis would be mirrored in the contributions, leading us to refer to this project as "VITA". Since many of the authors have known Christoph for much longer than we have, we feel that the contributions themselves give a better insight into his f- mer and present work than we possibly could. On that note, we hope Christoph enjoys reading this Festschrift and wish him all the best for his future. The editors wouldlike to thank everyonewho showedinterestin this project, especially the authors for their contributions and the organisers of the col- quium. Furthermore we would like to thank Kai Sachs for his work in coordin- ing this Festschrift with Springer.
