报告摘要：
Partitions with restricted parts in many different settings have been extensively studied. An interesting new subject is the study of the bias phenomenon, which focuses on the tendency of some parts to appear more frequently than others in the partitions. Quantitative and qualitative research have been carried out on such phenomena. In this talk, we will show how to explicitly measure the biases of the appearance of parts from two certain finite sets. We also address a problem of Stanley concerning explicit bijections between partitions into restricted （distinct and bounded) parts of a number divisible by n and binary necklaces of n heads. Joint work with Sicheng Zhao and Yanghongbo Zhou.
