Query: RNA Folding and Large N Matrix Theory   We formulate the RNA folding problem as an $N\times N$ matrix field theory.
This matrix formalism allows us to give a systematic classification of the
terms in the partition function according to their topological character. The
theory is set up in such a way that the limit $N\to \infty$ yields the
so-called secondary structure (Hartree theory). Tertiary structure and
pseudo-knots are obtained by calculating the $1/N^2$ corrections to the
partition function. We propose a generalization of the Hartree recursion
relation to generate the tertiary structure.
