One solves Markov moment and Mazur-Orlicz problems in concrete spaces of functions and respectively operators. One uses earlier results, as well as recent theorems on the subject. One characterizes the existence of a solution, or one gives sufficient cond... see more

One recalls the relationship between the Markov moment problem and extension of linear functionals (or operators), with two constraints. One states necessary and sufficient conditions for the existence of solutions of some abstract vector-valued Markov mo... see more

Existence and construction of the solutions of some Markov moment problems are discussed. Starting from the moments of a solution, one recalls a method of recovering this solution, also solving approximately related systems with infinite many nonlinear eq... see more

El problema de la «movilidad social» constituye un tópico clásico en la ciencia social y ha tenido diversos abordajes. En este trabajo se presentan algunas herramientas metodológicas para el análisis de la movilidad social en matrices de transición. Se di... see more

The main purpose of this review-paper is to recall and partially prove earlier, as well as recent results on convex optimization, published by the author in the last decades. Examples are given along the article. Some of these results have been published ... see more

The base system in this paper uses Hidden Markov Models (HMMs) to model dynamic relationships among facial features in facial behavior interpretation and understanding field. The input of HMMs is a new set of derived features from geometrical distances ob... see more

This paper's focal point is on the nonstandard Optimal Control (OC) problem. In this matter, the value of state variable, y(T) at the final moment, T is said to be free and unknown. Moreover, the Lagrangian integrand in the function is in the form of a pi... see more

Berezin-Klauder-Toeplitz (“anti-Wick”) or “coherent state” quantization of the complex plane, viewed as the phase space of a particle moving on the line, is derived from the resolution of the unity provided by the standard (or gaussian) coherent states. T... see more

The Republic of Crimea and Sevastopol are multinational regions and, thus, the problem of inter-ethnic harmony in them was relevant at various periods of history. It remains extremely important at the moment, taking into account the new information, digit... see more
