Extremal functions on moduli spaces and applications

Autor: Glazunov, Nikolaj

We construct and study extremal functions, which are defined by distance functions of convex bodies. Such functions take values in the moduli spaces of geometric objects associated with these convex bodies. Examples of such functions are the homogene

This paper explores the use of reverberation chambers for TRP measurements of beamformed radiation by phased arrays at mmWave frequencies. First, the received power was verified by the one-sample K-S GoF test to follow the exponential probability dis

On coverings by Minkowski balls in the plane and a duality

Autor: Glazunov, Nikolaj

Lattice coverings in the real plane by Minkowski balls are studied. We exploit the duality of admissible lattices of Minkowski balls and inscribed convex symmetric hexagons of these balls. An explicit moduli space of the areas of these hexagons is co

Objective. Currently, for the development of Valanginian and other deeplying (compared to the Cenomanian) deposits, low-temperature separation (LTS) units with turboexpander units (TDA) are used, and the booster compressor station (BCS) is one of the
