ON THE SMOOTHNESS OF SOLUTIONS OF DEGENERATE ELLIPTIC EQUATIONS
Mathematics of the USSR-Izvestiya, 1968It is shown that under broad assumptions the generalized solution of boundary problems for degenerate second-order equations satisfies a Holder condition. An example is given which shows that increasing the smoothness of the data of the problem cannot alone achieve greater smoothness of the solution.

Homogenization of degenerate elliptic‐parabolic equations
Asymptotic Analysis, 2004In 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 μ(x)∂ t −div(a(x,t)·D) where the quadratic form associated to a(x,t) is degenerating as a Muckenhoupt weight and the ...

Homogenization of degenerate elliptic equations
Siberian Mathematical Journal, 2008Summary: We consider divergent elliptic equations whose weight function and its inverse are assumed to be locally integrable. The equations of this type exhibit the Lavrentiev phenomenon, the nonuniqueness of weak solutions, as well as other surprising consequences.

On the Continuous Solutions of a Degenerate Elliptic Equation
Proceedings of the London Mathematical Society, 1985Dans cet article l'A. étudie l'équation \(-(\phi a^{ij}u_{x_ i})_{x_ j}+a^ iu_{x_ i}+a^ 0u=f\) dans \(\Omega\) où \(\phi\) est equivalent à la distance de x à \(\partial \Omega\). Il précise des conditions d'existence de solutions dont il donne la régularité.
