摘要:
This paper concerns the existence and multiplicity of positive solutions to the nonresonant second-order boundary-value problem Lx = lambda w(t)f(t, x). We are interested in the operator Lx := -x '' + rho qx when w is in L-p for 1 <= p <= +infinity. Our arguments are based on fixed point theorems in a cone and Holder's inequality. The nonexistence of positive solutions is also studied.
