PREFACE
Raoul Bott lecturing at Gökova Conference, 1996
We dedicate this volume to the memory of Raoul Bott, a great mathematician of the
20th Century. He is well known for his amazing work on the periodicity of the homotopy groups of Lie groups, and his contributions to index theory, foliations, equivariant
topology, and gauge theory. In recent years he was also active in TQFT and physics.
Raoul has been a long time supporter of Gökova Geometry Topology Conferences, which
he attended twice; he wrote articles to its proceedings, as well as giving organizational
support. He had a very warm and modest presence; interacting with him was not only a
source of mathematical stimulation, but at a personal level a great joy for everyone. In
these conferences he left a lasting impression, especially in younger mathematicians who
were in awe of him; when answering their questions he gently embraced them by their
shoulders like a Turkish grandfather. Raoul this modest volume is to you with all our
heartfelt respect.
This proceedings volume contains articles from both eleventh and twelfth Gökova
Conferences. Thanks to TÜBİTAK’s continuous support since 1992, Gökova Geometry
Topology Conferences have flourished greatly and have had a strong impact. TÜBİTAK
has published all the previous issues of the conference proceedings. This is the first year
we receive support from NSF. We thank NSF for their generous support as well.
