✦ Synopsis

The magnetosphere of a compact stellar object with an accretion disc is considered. Using the method of conformal mapping, the shapes of the magnetosphere and the accretion disc and, also, the configuration of the magnetic field within the limits of the magnetosphere are obtained in a self-consistent manner in the approximation of ideal magnetohydrodynamics. The dependence of the solution on the parameters is investigated. The proposed model is related to neutron stars (magnetars, in particular) and white dwarfs.

## Abstract A class of higher order compact (HOC) schemes has been developed with weighted time discretization for the two‐dimensional unsteady convection–diffusion equation with variable convection coefficients. The schemes are second or lower order accurate in time depending on the choice of the

A numerical method for a nonlinear inversion problem for the 2D wave equation with a potential is discussed. In order to avoid the ill-posedness, we substitute a coupled system of one-way wave equations for the original wave equation. An iterative algorithm is constructed to improve the accuracy of

In this paper, we consider two dependent classes of insurance business with heavy-tailed claims. The dependence comes from the assumption that claim arrivals of the two classes are governed by a common renewal counting process. We study two types of ruin in the two-dimensional framework. For each ty
