EXISTENCE AND REGULARITY OF POSITIVE SOLUTIONS OF THE ELLIPTIC EQUATIONS INVOLVING CRITICAL NONLINEAR AND SUBLINEAR

0 IntroductionLet Ωbe a smooth bounded domain in R~n with n>3, consider the problem of finding a function u(x)which satisfieswhere 0<α<1, 1 1 there is asolution of (0. 1) for any λ>0.The principal tecncihique of argument in 1] is using positive radial solution (0. 3) of equation -△u=u~2~n-1 in R~*.
