        摘要：
        Partition of diagram monoids first appeared in 1937 in a paper by Brauer in which they served as vector space bases of certain associative algebras relevant in representation theory of classical groups. Other species of diagram monoids were invented by Temperley and Lieb in the context of statistical mechanics in the 1970s and by Kauffman and Jones in the context of knot theory in the 1980s. Since then diagram monoids have revealed many other connections, e.g., with low-dimensional topology, topological quantum field theory, quantum groups etc.Recently, they have been intensively studied as purely algebraic objects, and these studies have shown that diagram monoids are quite interesting from this viewpoint as well.
        In the talk, we will introduce some algebraic properties of monoids of diagrams and 2-cobordisms.
