摘要
We prove, under assumptions lg rho(u) concave a(x, u, xi)/rho(u) increasing in u, existence and uniqueness of solutions u is an element of W(1.p)(Omega) boolean AND L(infinity)(Omega) to equations of the form -Sigma(n)(i=1) partial derivative/partial derivative x(i) [rho(u)b(i) (x, partial derivative u/partial derivative x)] + a (x, u, partial derivative u/partial derivative x) =0 x is an element of Omega.
