Laplace Equation, Polar Singularity, Dirichlet ProblemAbstract
In a bounded domain on a plane, a second-order elliptic equation with a polar singularity in the lower-order coefficient is considered, whose principal operator is the Laplace operator. The problem of constructing an explicit integral representation of the general solution is studied. The case with a first-order polar singularity is considered separately using a modified Pompeiu – Vekua integral. The obtained integral representation is applied to find the unique solution of the Dirichlet-type problem. The obtained explicit solution of the considered equation also allows for the direct formulation and investigation of linear conjugation and Riemann – Hilbert type problems.
