A steepest descent calculation of RNA pseudoknots
arXiv:physics/0207110 · doi:10.1103/PhysRevE.72.011911
Abstract
We enumerate possible topologies of pseudoknots in single-stranded RNA molecules. We use a steepest-descent approximation in the large N matrix field theory, and a Feynman diagram formalism to describe the resulting pseudoknot structure.
