In den WarenkorbTaschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The international conference on the Foundations of Software Technology and Theoretical Computer Science (FSTTCS) is the longest-running conference on computer science in India, and is organized under the aegis of the Indian As- ciation for Research in Computing Science, IARCS. Since its inception in 1981, the conference (held annually in the month of December) has helped in nurt- ing and creating an environment for the exchange of ideas amongst the research community in the country, by attracting top scientists around the world to the conference. This volume contains the proceedings of the 24th FSTTCS conf- ence held in December 2004. A strong point of the FSTTCS programmes has been excellent invited talks by eminent computer scientists of international renown. Continuing this t- dition, this FSTTCS featured invited talks by Javier Esparza, Piotr Indyk, Pavel A. Pevzner, John C. Reynolds, and Denis Th erien. We thank our invited speakers for readily agreeing to come to FSTTCS, and for providing write-ups for the proceedings. It is our pleasure that IARCS chose to honor Prof. Rani Siromoney at this conference, on the occasion of her 75th birthday. The in uence she has wielded (and the impact she has exerted) in Indian theoretical computer science is tremendous, and the tribute is tting and richly deserved. We thank R.K. Sh- masundar for chairing the special session in her honor, and Kamala Krithivasan and K.G. Subramanian for speaking at the session.

The conference was held at the Indian Institute of Technology, Kanpur during December 12-14, 2002. The conference attracted 108 submissions (of which two were withdrawn). Of these, a total of 26 papers were selected for presentation in the conference. As in the last year, the PC meeting was held electronically (stretching over nearly three weeks in August 2002) and was a great success. In addition to the contributed papers, we had ve invited speakers this year: Hendrik Lenstra, Jr., Harry Mairson, Dale Miller, Chih-Hao Luke Ong, and Margus Veanes. We thank them for accepting our invitation and for providing abstracts (or even full papers) for the proceedings. Two workshops were organized in conjunction with the conference - both in Kanpur. A workshop on Parameterized Complexity was held during December 10-11, organized by Mike Fellows and Venkatesh Raman. The second workshop actually consisted of three miniworkshops: on Coding Theory by Madhu Sudan; on Finite Field Algorithms by Hendrik Lenstra, Jr.; and on Sieve Theory by R. Balasubramanian. We wish to thank all the reviewers and PC members who contributed greatly to making the conference a success. We also wish to thank the team at Springer- Verlag for their help in preparing the proceedings.

This year sconference attracted 141 submissions(of which 5 werewithdrawn) from over 25 countries. Each submission was reviewed by at least three referees, with most receiving more than four reviews. The Program Committee met in New Delhi on 5 and 6 August 2000, with many members participating electr- ically over the Internet. The discussions continued over the Internet for several days and we nally selected 36 papers for presentation at the conference and inclusion in the proceedings. We thank the Program Committee for their - perlative e orts in nding top quality reviewers and working extremely hard to ensure the quality of the conference.
