Bondarevbondarev.b@mail.ru<h2>This article focuses on how quantum mechanics has been discovered and developed over the past century, and how its development has been hindered by many false theories. 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>2021-02-13T05:17:35+00:00##submission.copyrightStatement##http://scitecresearch.com/journals/index.php/jprm/article/view/2018Sum Formulas For Generalized Tetranacci Numbers: Closed Forms of the Sum Formulas ∑_{k=0}ⁿx^{k}W_{k} and ∑_{k=1}ⁿx^{k}W_{-k}2021-02-19T14:58:31+00:00Yüksel Soykanyuksel_soykan@hotmail.com<p>In this paper, closed forms of the sum formulas ∑_{k=0}ⁿx^{k}W_{k} and ∑_{k=1}ⁿx^{k}W_{-k} for generalized Tetranacci numbers are presented. As special cases, we give summation formulas of Tetranacci, Tetranacci-Lucas, and other fourth-order recurrence sequences.</p>2021-02-19T14:56:33+00:00##submission.copyrightStatement##http://scitecresearch.com/journals/index.php/jprm/article/view/1979Estimates of Fekete-Szego Functional of a Sub- class of Analytic and Bi-Univalent Functions by Means of Chebyshev Polynomials2021-02-24T14:49:45+00:00Rasheed Olawale Ayinlarasheed.ayinla@kwasu.edu.ng<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>2021-02-24T14:49:45+00:00##submission.copyrightStatement##http://scitecresearch.com/journals/index.php/jprm/article/view/2022Distributed Control for Non-Cooperative Systems Under Conjugation Conditions2021-03-03T04:51:48+00:00A. A. Alsabanahmedalsaban@yahoo.comH. M. Seragserraghm@yahoo.comLamiaa Mohamed Abdelrhmanlamiaa3461@gmail.com<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>2021-03-03T04:36:51+00:00##submission.copyrightStatement##http://scitecresearch.com/journals/index.php/jprm/article/view/2035Studies On the Recurrence Properties of Generalized Pentanacci Sequence2021-04-06T09:47:47+00:00Yüksel Soykanyuksel_soykan@hotmail.com<p>In this paper, we investigate the recurrence properties of the generalized Pentanacci sequence and present how the generalized Pentanacci sequence at negative indices can be expressed by the sequence itself at positive indices.</p>2021-04-06T09:47:47+00:00##submission.copyrightStatement##
