SINGULAR (n-1,1) CONJUGATE BOUNDARY VALUE PROBLEMS

摘要

In this paper, we study the existence of nonnegative solutions of singular (n ― 1,1) conjugate boundary value problem u~((n)) + a(t)f(u) = 0 with boundary value conditions u~((k))(0) = 0 (0 ≤ k ≤ n ― 2) and u(1) = 0. Where a(t) may have finitely many singularities. Our results essentially generalized paper and other related literature (for example [4]).
