In this paper, we investigate the inverse problem of a simple layer potential where, by the known values of the potential gradient given as a finite series in a neighborhood of the point at infinity, we search for a simple closed contour with gravita

With the help of Cauchy-type integrals, a new derivation of integral equations for solving logarithmic potential problems is given. A variant of the inverse logarithmic potential problem with two starlike solutions is analyzed; it contains fewer para

We discuss the capabilities of A. V. Tsirulsky’s method in the solution of direct problems of the logarithmic potential. We give classification of the Schwarz functions that arise in construction of the solutions and study the cases of finite-sheet

We obtain a new class of solutions to the inverse problems of the logarithmic potential in the form of a logarithmic function of a ratio of polynomials of the same degree. We give examples of finite solvability of the inverse problems.

We introduce Gakhov’s radius as the radius of the largest circle rE, 0 < r ≤ 1, E = {ζ: |ζ| < 1}, inside of which the external inverse boundary value problem possesses unique solution. We find the Gakhov’s radius and convexity radius for seve

The article presents new explicit forms of the Schwarz integral in an annulus. Some correspondence is obtained between the Fourier series for the boundary values of the Schwarz problem and the Laurent series for a regular function f(z) that is the so
