Mq. Yu et Xt. Liang, EVERYWHERE HOLDER CONTINUITY OF SOLUTIONS OF CERTAIN DEGENERATE ELLIPTIC-SYSTEMS, Journal of mathematical analysis and applications, 203(3), 1996, pp. 654-671
Consider on G a degenerate elliptic system in diagonal farm of which s
olutions are in a weighted Sobolev space with weight function that bel
ongs to the Muckenhoupt class A(2) and characteristic values of the le
ading coefficient matrix that are proportional to a positive power of
the modulus of the unknown solution. The everywhere Holder continuity
in the interior of G is proved to bounded solutions. (C) 1996 Academic
