ANNOTATION
The article studies the equation obtained by double iterating an ordinary differential operator of the first order with boundary and internal weakly singular point. Representation formula of the general solution of the equation is found, which is applied to the study of the properties of solutions, their behavior in the neighborhood of a singular point, the formulation and solution of Cauchy - Ryke type problems with conditions at a weakly singular point. It is shown that the solutions of the equation and the value of the corresponding operator from them in the neighborhood of the weakly singular point remain bounded. The presence of a singularity in the equation affects the formulation of boundary value problems and is expressed in the fact that it will be sufficient to set the conditions on a part of the boundary.
KEY WORDS
