ABOUT WAVEFUNCTIONS IN LOW-DIMENSIONAL SEMICONDUCTORS
The impressive progress in the fabrication of low-dimensional semiconductor structures during the past two decades has made it possible to reduce the effective device dimension from three-dimensional bulk materials, to quasi-two dimensional quantum well systems, to quasi-one dimensional quantum...

STABILITY OF FINITE DIFFERENCE SCHEMES FOR SIMMETRIC HYPERBOLIC SYSTEMS
In this article we investigate the stability of the finite difference schemes using the Neumann method for symmetric hyperbolic systems. For the two-dimensional symmetric hyperbolic system, the condition of the Lax-Wendroff scheme stagnation has been studied. To check for resilience using MathCad...

INTERCAPACITANCE BETWEEN TWO CHARGES LOCATED IN THE DIFFERENT ENVIRONMENTS
It is investigated the dependence of intercapacitance between two point charges located in different environments on the relative position of border. The image method is used. It is considered two cases: the charges is located at line which is perpendicular to the border and the charges is located...

CYCLIC SURFACES IN THE PSEUDOEVKLIT REGION
The article describes the hypothesis of the cyclic surface determined in the Galileo domain, the smallest dimensional pseudo-squid space, which is summarized in the five-dimensional two-indexed pseudo-squidoid space and then on the full cyclic surface. Full-scale surfaces have been proven to be in...
