摘要
In this paper, we are concerned with the second order self-adjoint boundary value problem at resonance -(p(t)x' (t))' = f(t; x(t)), t is an element of (0, 1), x'(0) = 0, x(1) = integral(1)(0) x(s)g(s)ds. A few new results are given for the existence of at least one, two, three and n positive solutions of the above boundary value problem by using the theory of a fixed point index for A-proper semilinear operators defined on cones, where n is an arbitrary natural number.
