报告摘要: We first give definitions and properties of combinatorial Hopf algebras. Then we introduce the theory of symmetric functions including different bases, Schur functions, RSK algorithm and self-duality. We end with a series of open questions regarding multivariate dual graded graphs and two Hopf algebras as examples: non-commutative symmetric functions, and graphs with two types of vertices.
