摘要: This paper considers the following boundary value problems for functional differential equations: x' (t) = f(t, xt) (0<t<b) ,x0 = x1, and x"(t) = f(t,xt, x' (t)) (0<t<b) , x(b) = B. By using certain fixed point theorem based on degree theory,some sufficient conditions for solvability of the above problems are given.
