n this paper we give a result of G-convergence for a class of strongly degenerate parabolic equations in the case of periodic coefficients. The operators have the form mu(x)partial derivative(t)-div(a(x,t).D) where the quadratic form associated to a(x,t) is degenerating as a Muckenhoupt weight and the coefficient mu is greater or equal to zero, possibly mu=0, that is the operator may be elliptic, parabolic or elliptic-parabolic.

Abstract
n this paper we give a result of G-convergence for a class of strongly degenerate parabolic equations in the case of periodic coefficients. The operators have the form mu(x)partial derivative(t)-div(a(x,t).D) where the quadratic form associated to a(x,t) is degenerating as a Muckenhoupt weight and the coefficient mu is greater or equal to zero, possibly mu=0, that is the operator may be elliptic, parabolic or elliptic-parabolic.File in questo prodotto:
