Nature of the physical problem
In this communication, we describe accurate finite difference techniques for the solution of the Dirichlet problem in cylin-drical coordinates with axially symmetric boundary conditions. The program package can be used for the calculation of the capacitance Of ring capacitors.

This paper studies the existence of symmetric positive solutions for a second-order nonlinear ordinary differential equation with integral boundary conditions by applying the theory of fixed point index in cones. For the demonstration of the results, an illustrative example is presented.
In this paper, we consider the Dirichlet problem involving the p(x)-Kirchhoff-type We prove the existence of infinitely many non-negative solutions of the problem by applying a general variational principle due to B. Ricceri and the theory of the variable exponent Sobolev spaces.
By using the Weinstein method, eigenvalues and eigenfunctions ofthe equation -zau = Au with Dirichlet boundary conditions are calculated for a certain class of regions. The regions are composed of unions of rectangles, and include L-shaped, single-notched and crossed rectangles. The method consists
