TITLEChen’s Grammars and Several Applications in Combinatorics (I)

ABSTRACT In this talk, we present a survey of our work on the study of Chen’s grammars (which is also known as context-free grammars). We first present the grammars for Eulerian polynomials of types A and B, the q-Eulerian polynomials, derangement polynomials of types A and B, the 1/k Eulerian polynomials. We then present the study on the 1/k Eulerian polynomials. Some problems are also discussed.
