C.S. Seshadri turned seventy on the 29th of February, 2002. To mark this occasion, a symposium was held in Chennai, India, where some of his colleagues gave expository talks highlighting Seshadri's contributions to mathematics. This volume includes expanded texts of these talks as well as research and expository papers on geometry and representation theory. It will serve as an excellent reference for researchers and students in these areas.

The beauty of great card play at bridge is something we can all admire, even if we can't all aspire to the heights reached by top-class players. Some of the greatest players seem almost to operate instinctively, and most of us probably feel that we could never hope to play at that level. Perhaps, though, if we understood more about their thought processes, it might be possible. The author presents 50 problems in play and defence taken from tournament play, giving the reader a chance to solve them for himself before any discussion takes place. Each problem is analysed, sometimes in great detail, to show how the logic of the situation, when looked at correctly, can lead players at any level to the 'right' solution. But in each case, the reader may be left feeling that the neat, elegant solution is 'easier done than said'!
