In this paper, we study the existence of entropy solution for quasilinear elliptic equations of the form, for some right-hand side datum f in L 1 (Ω). Note that g(x, s, ξ) is a non-linear term which has a growth condition with respect to ξ and no growth with respect to s, but it satisfies a sign condition on s.(x)-solutions for nonlinear elliptic equations… (More)

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. An RNA molecule is a heteropolymer strand made up of four types of nucleotides, uracil (U), adenine (A), guanine (G), and… (More)
