Some of these theories have come to light because a new tool has not yet been born that would ensure the existence of new theories. Other false quantum theories appeared due to the authors ignorance of the basics of quantum mechanics and are still taught to students.</h2> <h2>This work opens up new paths of quantum physics that start with the Lindblad equation for the statistical operator and the equation for the density matrix. The last equation is equivalent to the equation for the statistical operator.</h2> Boris V.

As special cases, we give summation formulas of Tetranacci, Tetranacci-Lucas, and other fourth-order recurrence sequences.</p> Yüksel Soykan ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 http://scitecresearch.com/journals/index.php/jprm/article/view/2018 Fri, 19 Feb 2021 14:56:33 +0000 Estimates of Fekete-Szego Functional of a Sub- class of Analytic and Bi-Univalent Functions by Means of Chebyshev Polynomials http://scitecresearch.com/journals/index.php/jprm/article/view/1979 <p>In this work, a new subclass C( ; ; n; t) of analytic and bi-univalent functions is dened by subordination principle and investigated. The initial coecient bounds and the upper estimates of the Fekete-Szego functional were obtained using Chebyshev polynomials.</p> Rasheed Olawale Ayinla ##submission.copyrightStatement## http://creativecommons.org/licenses/by-nc/4.0 http://scitecresearch.com/journals/index.php/jprm/article/view/1979 Wed, 24 Feb 2021 14:49:45 +0000 Distributed Control for Non-Cooperative Systems Under Conjugation Conditions http://scitecresearch.com/journals/index.php/jprm/article/view/2022 <p>In this paper, the distributed control for non-cooperative elliptic systems under conjugation conditions is established. First, the existence and uniqueness of the state for these systems with Dirichlet and conjugation conditions is proved, then the set of equations and inequalities that characterizes the distributed control of these systems is found. The non-cooperative Neumann systems with conjugation conditions is also discussed.</p> A. A. Alsaban, H. M.
