Analysis by the Method of Two-Sided Approximations of Positive Axially Symmetric Solutions of the First Boundary Value Problem for the Helmholtz Equation with a Singular Power Nonlinearity

The paper analyzes, by means of the method of two-sided approximations, positive axially symmetric solutions of the first boundary value problem for a semilinear elliptic differential equation with the Helmholtz operator and a singular power nonlinearity. The problem is considered in a circular doma...
