Main Article Content
Abstract
In this paper, we prove existence results for the singular problem (−1)n−p(Φmx(n−1))′ (t)=μf(t,x(t),…,x(n−1)(t)), for 0<1, x(i)(0)=0, i=0,1,…,p−1, x(i)(1)=0, i=p, p+1,…,n−1, max{x(t):t∈[0,1]}=A. The paper presents conditions which guarantee that for any A>0 there exists μA>0 such that the above problem with μ=μA has a solution x∈Cn−1([0,1]) with Φm(x(n−1))∈AC([0,1]) which is positive on (0,1). Here the positive Carath\'edory function f may be singular at the zero value of all its phase variables. Proofs are based on the Leray-Schauder degree and Vitali's convergence theorem.
