Abstract. In this paper, we consider a nonlinear integro-differential problem with a zero operator of the differential part, the integral operator of which contains a rapidly changing kernel, and the right-hand side depends on a rapidly oscillating exponent. This work is a continuation of the research carried out earlier for a similar linear system with a rapidly changing kernel. In the nonlinear case, the conditions for the solvability of the corresponding iterative problems, as in the linear case, will have the form not of differential (as was the case in problems with a nonzero operator of the differential part), but of integro-differential equations, and the formation of these equations is played by nonlinearity and rapidly oscillating inhomogeneity
