SEMINAR: Groups and Combinatorics Seminar: On the lambda-design conjecture

Groups and Combinatorics Seminar

Akos Seress (UWA)

will speak on

On the lambda-design conjecture

at 12 noon in MLR2 on Tuesday 5th of April.

Abstract:

A lambda-design is a set system consisting of v sets on a v-element underlying set so that any two distinct members intersect in exactly lambda points and not all sets are of the same size.

Ryser and Woodall's lambda-design conjecture states that all lambda-designs can be obtained from symmetric designs a certain block-complementation procedure. We report about recent efforts toward the solution of this conjecture.

All welcome
