Direct Problem for Gas Diffusion in Polar Firn with Variable Coefficients
Proves existence and uniqueness for a degenerate parabolic PDE modeling gas trapping in firn with variable D(z) and f(z) using weighted Sobolev spaces and Lions' theorem, plus conditions for a P1 finite-element plus implicit-Euler discretization.
