TL;DR: The first result on the ternary Goldbach problem with missing digits was given in this article , which merges methods of Maynard from his paper on the infinitude of primes with restricted digits, results of Balog and Friedlander on Piatetski-Shapiro primes and the Hardy-Littlewood circle method in two variables.
Abstract: Let [Formula: see text] Let [Formula: see text], [Formula: see text] be fixed. Let also [Formula: see text]. We prove on assumption of the Generalized Riemann Hypothesis that each sufficiently large odd integer [Formula: see text] can be represented in the form [Formula: see text] where the [Formula: see text] are of the form [Formula: see text], [Formula: see text], for [Formula: see text] and the decimal expansion of [Formula: see text] does not contain the digit [Formula: see text]. The proof merges methods of Maynard from his paper on the infinitude of primes with restricted digits, results of Balog and Friedlander on Piatetski-Shapiro primes and the Hardy–Littlewood circle method in two variables. This is the first result on the ternary Goldbach problem with primes of mixed type which involves primes with missing digits.

TL;DR: In this article, the authors investigate the possibility of destroying a passive point target and determine the best targeting points in an area within which stationary or mobile targets are distributed uniformly or normally.
Abstract: First, we investigate the possibility of destruction of a passive point target. Subsequently, we study the problem of determination of best targeting points in an area within which stationary or mobile targets are distributed uniformly or normally. Partial results are given in the case in which the number of targeting points is less than seven or four, respectively. Thereafter, we study the case where there is no information on the enemy distribution. Then, the targeting should be organized in such a way that the surface defined by the kill radii of the missiles fully covers each point within a desired region of space-time. The problem is equivalent to the problem of packing ellipsoids of different sizes and shapes into an ellipsoidal container in \(\mathbb{R}^{4}\) so as to minimize a measure of overlap between ellipsoids is considered.

TL;DR: This paper investigates the method of selective priorities for the data amounts in the processing of big data by defining the focal data sets and the concept of program of data selection which specifies the data amount that a processor may take into account.
Abstract: This paper investigates the method of selective priorities for the data amounts in the processing of big data. After defining the focal data sets, it is introduced the concept of program of data selection which specifies the data amount that a processor may take into account. Then, they are determined the relations of data selection preference and of rational choice for the data amounts. Subsequently, it is considered the case of several data processors and it is shown that there are cores and equilibriums of contrasts, the study of which may provide useful information.

TL;DR: In this paper, new results concerning three dimensional real hypersurfaces in non-flat complex space forms in terms of their stucture Jacobi operator are presented, and the conditions of 1) the structure Jacobi operators being of Codazzi type with respect to the generalized Tanaka-Webster connection and commuting with the shape operator and 2) η-invariance of the structureJacobi operator and commutativity of it with shape operator are studied.
Abstract: In this paper new results concerning three dimensional real hypersurfaces in non-flat complex space forms in terms of their stucture Jacobi operator are presented. More precisely, the conditions of 1) the structure Jacobi operator being of Codazzi type with respect to the generalized Tanaka-Webster connection and commuting with the shape operator and 2) η-invariance of the structure Jacobi operator and commutativity of it with the shape operator are studied. Furthermore, results concerning Hopf hypersurfaces and ruled hypersurfaces of dimension greater than three satisfying the previous conditions are also included.
