In this work we study the degenerate diffusion equation ∂t=xαa(x)∂x2+b(x)∂x for (x,t)∈(0,∞)2, equipped with a Cauchy initial data and Dirichlet boundary condition at 0. We assume that order of degeneracy 0 operator is α∈(0,2), coefficient functions (and their derivatives) are only locally bounded. adopt combination probabilistic approach analytic method: by analyzing behaviors underlying proces...
