Existence and multiplicity of positive solutions for singular semipositone $p$-laplacian equations
(Canadian Mathematical Society, 2006-06-01)Positive solutions are obtained for the boundary value problem [GRAPHICS] Here f(t, u) >= -M, (M is a positive constant) for (t, u) is an element of [0, 1] X (0, infinity). We will show the existence of two positive ... -
