On self-complementary Distance-regular Cayley Graphs


Self-complementary graphs are related to diagonal Ramsey numbers. In this talk we give some properties of self-complementary distance-regular Cayley graphs.

The Combinatorics of Higher Derived Limits


This talk will divide, within a single session, into two parts. Its first half will survey main developments in the set theoretic study of the derived functors of the inverse limit, much of which traces to the 1988 question of the consistency of the additivity of strong homology. This question was recently resolved, and the second half of the talk will focus on a family of partition principles that underlay its solution. We will not assume of our audience any particular background in these subjects, least of all in the first half of the talk and we should perhaps emphasize that what most fundamentally interests us in this material are ...
