Ray methods for free boundary problems
We discuss the use of the WKB ansatz in a variety of parabolic problems involving a small parameter. We analyse the Stefan problem for small latent heat, the Black-Scholes problem for an American put option, and some nonlinear diffusion equations, in each case constructing an asymptotic solution by...
