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 Monotone Power Nonlinearity

The paper presents an analysis, using the method of two-sided approximations, of positive axially symmetric solutions to the first boundary value problem for a semilinear elliptic differential equation with the Helmholtz operator. The domain in which the problem is considered is a disk, on the bound...
