Combining the approaches of functionals associated with h-concave functions
and fixed point techniques, we study the existence and uniqueness of a
solution for a class of nonlinear integral equation: x(t) = g1(t)-g2(t) +
? ?t,0 V1(t,s)h1(s,x(s))ds + ? ?T,0 V2(t,s)h2(s,x(s))ds; where C([0,T];R)
denotes the space of all continuous functions on [0,T] equipped with
the uniform metric and t?[0,T], ?,? are real numbers, g1, g2 ? C([0,
T],R) and V1(t,s), V2(t,s), h1(t,s), h2(t,s) are continuous real-valued
functions in [0,T]xR.
