On the regularity up to the boundary in the Dirichlet problem for degenerate elliptic equations. (English) Zbl 0681.35021
Regularity up to the boundary of solutions to certain factorizable second order degenerate elliptic equations in the plane satisfying Dirichlet boundary conditions are derived. This follows from the regularity up to the boundary for some pseudodifferential equations, using parametrices of the Cauchy problem for the associated heat equation.
