摘要：

In this paper we study critical points problems for some integral functionals with principal part having degenerate coerciveness, whose model is J(v) = (1)/(2) integral (Omega) (/delv/2) / ((b(x)+/v/)2 alpha) - (1)/(m) integral (Omega) /v/(m), v is an element of H-0(1)(Omega), with 1 < m < 2*(1 - alpha). We will prove several existence and nonexistence results depending on different assumptions on both m and alpha. (C) 2001 Editions scientifiques et medicales Elsevier SAS.
