There are 19 unpublished letters written by latter bishop of Zica Jefrem Bojovic, preserved in The Manuscripts Department Russian State Library Moscow. These letters, addressed to Nil Alexandrovich Popov, part a personal collection this famous scholar the field history and Slavic literature. Letters from were 1874 until 1886, while Bojovic was student at Moscow Spiritual Academy professor Semin...

We derive diierent representations of compact QED xed to Lan-dau gauge by the lattice Faddeev-Popov procedure. Our analysis nds that (A)Nielsen-Olesen vortices arising from the compactness of the gauge-xing action are quenched , that is, the Faddeev-Popov determinant cancels them out and they do not innuence correlation functions such as the photon propagator; (B)Dirac strings are responsible f...

We discuss the problem of gauge fixing for the partition function in generalized quantum (or trace) dynamics, deriving analogs of the De WittFaddeev-Popov procedure and of the BRST invariance familiar in the functional integral context.

In this paper, we investigate the applicability of different theories on intensity-dependent ionization rate for C2+ atomic targets at laser wavelengths (frequency) and linear polarization. We use analytical formulas draw conclusions, from numerical comparison with results ab initio ‘two-state model’ R-matrix Floquet calculation, their correct predictions rate. The single-photon has been studie...

This document describes the cryptographic algorithms and parameters supplementary to the original GOST specifications GOST 28147-89, GOST R 34.10-94, GOST R 34.10-2001 and GOST R 34.11-94 for use in Internet applications. Table of

The extinct members of the Psallopinae are important for classifying and understanding the relationships among the closely related mirid groups Isometopinae, Psallopinae (sensu Schuh, 1976) and Cylapinae. These subfamilies are considered to be the most primitive sister groups among mirids and their taxonomical composition, geographical distribution and life history are still poorly known. Extan...

We give modular algorithms to compute row-reduced forms, weak Popov forms, and Popov forms of polynomial matrices, as well as the corresponding unimodular transformation matrices. Our algorithms improve on existing fraction-free algorithms. In each case we define lucky homomorphisms, determine the appropriate normalization, as well as bound the number of homomorphic images required. The algorit...

Robust performance analysis plays an important role in the design of controllers for uncertain multivariable systems. Recent research has investigated the use of absolute stability criteria to develop less conservative analysis tests for systems with linear and nonlinear real parameter uncertainties. This note extends previous work on optimal X2 performance analysis using the Popov criterion by...

Let G be a split simple group of type G2 over a field k, and let g be its Lie algebra. Answering a question of J.-L. Colliot-Thélène, B. Kunyavskĭi, V. L. Popov, and Z. Reichstein, we show that the function field k(g) is generated by algebraically independent elements over the field of adjoint invariants k(g). Résumé. Soit G un groupe algébrique simple et déployé de type G2 sur un corps k. Soit...
