In this paper, we studied the Picard–Fuchs systems and equations which appear in the theory of Gauss–Manin systems and connections associated with deformations of isolated singularities. Among other things, we describe some interesting properties

In this paper, we discuss a few simple methods for computing the local topological index and its various analogs for vector fields and differential forms given on complex varieties with singularities of different types. They are based on properties o

A rigid body forced by a nonstationary perturbing torque with zero mean value is under consideration. The control strategy for attitude stabilization of the rigid body is based on the usage of dissipative and restoring torques. It is assumed that the

The study of bathymetry, macrozoobenthos abundance and the Russian desman population has been performed in the water bodies located in the Prisurskiy State Nature Reserve buffer zone (River Sura lower reaches floodplain). Twenty-one water bodies were

We discuss an approach to the problem of calculating the local topological index of vector fields given on complex spaces or varieties with singularities developed by the author over the past few years. Our method is based on the study of the homolog

The modern state legal mechanism for combating crime conceptually developed on the ideas of the classical understanding of the state and law. When transitioning to a digital socio-economic formation, its conceptual framework is subject to revision. T
