摘要
We consider the fourth-order two-point boundary value problem x'''' + kx '' + lx = f(t, x), 0 < t < 1, x(0) = x(1) = x'(0) = x'(1) = 0, which is not necessarily linearizable. We give conditions on the parameters k, l and f(t, x) that guarantee the existence of positive solutions. The proof of our main result is based upon topological degree theory and global bifurcation techniques.
