内容摘要:

In this talk, I will present some recent combinatorial studies of RNA secondary structures. The former part is concerned with a new bijection between RNA secondary structures and plane trees and its consequences. The latter part is about enumerating secondary structures taking into account the joint distribution of commonly known structural motifs including helices, hairpin loops, bulges, interior loops, exterior loops and multiloops. In particular, an algorithm (RakeSamp) generating uniformly random secondary structures that satisfy fine motif specifications on the length and degree of various types of loops as well as helices is introduced. The latter is a joint work with Christian Reidys and Michael Waterman.
