Description
Random partitions are of fundamental importance in many subjects, such as representation theory of symmetric groups, random permutations and random matrices. A central topic in the study of random partitions is to determine their asymptotic behavior such as limit shapes and fluctuations under Plancherel measures. In this talk, we will derive polynomiality results on several Plancherel type averages for certain functions of partitions by the difference operator technique, and use them to study limit shapes of random partitions and random strict partitions.
