The topological filtration of -structures
Thomas J. X. Li, Christian M. Reidys
In this paper we study -structures filtered by topological genus. -structures are a class of RNA pseudoknot structures that plays a key role in the context of polynomial time…

Combinatorial analysis of interacting RNA molecules
Thomas J. X. Li, Christian M. Reidys
Recently several minimum free energy (MFE) folding algorithms for predicting the joint structure of two interacting RNA molecules have been proposed. Their folding targets are inte…
