Abstract

In this paper, one class of nonlinear equations with the Cauchy – Riemann operator is considered. Such equation is reduced to a linear equation by a substitution; conditions under which this substitution makes a one-to-one mapping are formulated. The coefficient of the equation at the unknown function has an isolated strong power sinularity at zero, and after its elimitation it is continuously differentiable in a neighborhood of zero sufficiently many times. Using the Taylor expansion of the coefficient and direct integration of the polynomial part, by means of the Pompeiu – Vekua operator an integral representation of solutions to this equation is obtained.
