Pseudo-differential equations and conical potentials: 2-dimensional case

Vladimir B. Vasilyev

Abstract. We consider two-dimensional elliptic pseudo-differential equation in a plane sector. Using a special representation for an elliptic symbol and the formula for a general solution we study the Dirichlet problem for such equation. This problem was reduced to a system of linear integral equations and then after some transformations to a system of linear algebraic equations. The unique solvability for the Dirichlet problem was proved in Sobolev-Slobodetskii spaces and a priori estimate for the solution is given.

Keywords: pseudo-differential equation, wave factorization, Dirichlet problem, system of linear integral equations.

Mathematics Subject Classification: 35S15, 45A05.
