Zee %J Physics %D 2002 %I arXiv %R 10.1103/PhysRevE.72.011911 %X 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. %U http://arxiv.org/abs/physics/0207110v6
