Existence and uniqueness results for the integro-differential equation

u1(x,t)auxx(x,t)=c(x,t)u(x,t)+01k(s,x)h(s,t,u(s,t))ds+f(x,t) ((x,t)Q)u_1(x, t) - au_{xx} (x, t) = c(x, t)u(x, t) + \int^1_0 k(s, x)h(s, t, u(s, t)) ds + f(x, t)\\\ ((x,t) \in Q)

subject to the boundary condition

u(x,t)=φ(x,t) ((x,t)R)u(x,t) = \varphi (x,t)\\\ ((x, t) \in R)

and, especially, for the linear case h(s,t,u)=uh(s,t,u) = u are given. To this end, this equation is written as operator equation in a suitable Hölder space. The main tools are the calculation of the spectral radius in the linear case, and fixed point principles in the nonlinear case.
