Patterns in random permutations avoiding some sets of multiple patterns

Probability 2018-04-18 v1 Combinatorics

Abstract

We consider a random permutation drawn from the set of permutations of length nn that avoid some given set of patterns of length 3. We show that the number of occurrences of another pattern σ\sigma has a limit distribution, after suitable scaling. In several cases, the number is asymptotically normal; this contrasts to the cases of permutations avoiding a single pattern of length 3 studied in earlier papers.
