Title:Wilf-equivalence in permutation patterns
Seminar:Combinatorics/Partitions Seminar
Speaker:Andrew Baxter, PSU
Abstract:
In partition theory, it is often interesting when the number of partitions of n satisfying condition X equals the number of partitions satisfying condition Y. We will consider the analogous question for permutations of length n, where the conditions are phrased in terms of patterns which the permutations must avoid. Two patterns are Wilf-equivalent if the number of n-permutations avoiding one equals the number of n-permutations avoiding the other, and I will present some of the more powerful techniques to create such equivalences.
