Einstein, B. Podolsky and N. Rosen2020-01-20T17:18:36+01:00Ruggero Maria Santilliresearch@i-b-r.org<p>In this paper, we continue the study initiated in preceding works of the argument by A. Einstein, B. Podolsky and N. Rosen according to which quantum mechanics could be “completed” into a broader theory recovering classical determinism. By using the previously achieved isotopic lifting of applied mathematics into isomathematics and that of quantum mechanics into the isotopic branch of hadronic mechanics, we show that extended particles appear to progressively approach classical determinism in the interior of hadrons, nuclei and stars, and appear to recover classical determinism at the limit conditions in the interior of gravitational collapse</p>2019-12-30T00:00:00+01:00Copyright (c) 2019 Ruggero Maria Santillihttp://eiris.it/ojs/index.php/ratiomathematica/article/view/486Some results for Volterra integro-differential equations depending on derivative in unbounded domains2020-01-20T15:29:07+01:00Giuseppe Anichinigiuseppe.anichini@unifi.itGiuseppe Contigconti@unifi.itAlberto Trottaalbertotrotta@virgilio.it<p>In this paper we study the existence of continuous solutions of an integro-differential equation in unbounded interval depending on derivative This paper extend some results obtained by the authors using the technique developed in their previous paper. This technique consists in introducing, in the given problems, a function <em>q</em>, belonging to a suitable space, instead of the state variable <em>x. </em>The fixed points of this function are the solutions of the original problem. In this investigation we use a fixed point theorem in Fréchet spaces.</p>2019-12-30T00:00:00+01:00Copyright (c) 2019 Giuseppe Contihttp://eiris.it/ojs/index.php/ratiomathematica/article/view/485Solving some specific tasks by Euler's and Fermat's Little theorem2020-01-20T15:29:28+01:00Viliam Ďurišvduris@ukf.skEuler's and Fermat's Little theorems have a great use in number theory. Euler's theorem is currently widely used in computer science and cryptography, as one of the current encryption methods is an exponential cipher based on the knowledge of number theory, including the use of Euler's theorem. Therefore, knowing the theorem well and using it in specific mathematical applications is important. The aim of our paper is to show the validity of Euler's theorem by means of linear congruences and to present several specific tasks which are suitable to be solved using Euler's or Fermat's Little theorems and on which the principle of these theorems can be learned. Some tasks combine various knowledge from the field of number theory, and are specific by the fact that the inclusion of Euler's or Fermat's Little theorems to solve the task is not immediately apparent from their assignment.2019-12-30T00:00:00+01:00Copyright (c) 2019 Viliam Ďurišhttp://eiris.it/ojs/index.php/ratiomathematica/article/view/468Mahgoub Transform on Boehmians2020-01-20T15:29:49+01:00Yogesh Khandelwalyogeshmaths81@gmail.comPriti Chaudharypritichaudharyiitkgp@gmail.comBoehmian’s space is established utilizing an algebraic way that approximate identities or delta sequences and appropriate convolution. The space of distributions can be related to the proper subspace. In this paper, firstly we establish the appropriate Boehmian space, on which the Mahgoub Transformation can be described& function space K can be embedded. We add to more in this, our definitions enhance Mahgoub transform to progressively wide spaces. We additionally explain the functional axioms of Mahgoub transform on Boehmians. Lastly toward the finishing of topic, we analyze with specify axioms and properties for continuity and the enlarged Mahgoub transform, also its inverse regards to∆- convergence and δ.2019-12-30T00:00:00+01:00Copyright (c) 2019 Yogesh Khandelwal, Priti Chaudharyhttp://eiris.it/ojs/index.php/ratiomathematica/article/view/476On cyclic multigroup family2020-01-20T15:30:39+01:00Johnson Aderemi Awololaremsonjay@yahoo.comIn this paper, the concept of cyclic multigroup is studied from the preliminary knowledge of cyclic group which is a well known concept in crisp environment. By using cyclic multigroups, we then delineate a cyclic multigroup family and investigate its structure properties.2019-12-30T00:00:00+01:00Copyright (c) 2019 Johnson Aderemi Awololahttp://eiris.it/ojs/index.php/ratiomathematica/article/view/480A conceptual proposal on the undecidability of the distribution law of prime numbers and theoretical consequences2020-01-20T15:30:12+01:00Gianfranco Minatigianfranco.minati@airs.itWithin the conceptual framework of number theory, we consider prime numbers and the classic still unsolved problem to find a complete law of their distribution. We ask ourselves if such persisting difficulties could be understood as due to theoretical incompatibilities. We consider the problem in the conceptual framework of computational theory. This article is a contribution to the philosophy of mathematics proposing different possible understandings of the supposed<em> theoretical</em> unavailability and indemonstrability of the existence of a law of distribution of prime numbers. Tentatively, we conceptually consider demonstrability as computability, in our case the <em>conceptual availability</em> of an algorithm able to compute the general properties of the presumed primes’ distribution law <em>without computing such distribution</em>. The link between the conceptual availability of a distribution law of primes and decidability is given by considering how to <em>decide</em> if a number is prime <em>without</em> computing. The supposed distribution law should allow for any given prime knowing the next prime <em>without factorial computing</em>. <em>Factorial properties of numbers, such as their property of primality, require their factorisation (or equivalent, e.g., the sieves), i.e., effective computing. However, we have factorisation techniques available, but there are no (non-quantum) known algorithms which can effectively factor arbitrary large integers. Then factorisation is undecidable. We consider the theoretical unavailability of a distribution law for factorial properties, as being prime, equivalent to its non-computability, undecidability. </em>The availability and demonstrability of a hypothetical law of distribution of primes is inconsistent with its undecidability. The perspective is to transform this conjecture into a theorem.2019-12-30T00:00:00+01:00Copyright (c) 2019 Gianfranco Minatihttp://eiris.it/ojs/index.php/ratiomathematica/article/view/491Legendre Wavelet expansion of functions and their Approximations2020-01-20T15:36:42+01:00Indra Bhanindrabhanmsc@gmail.comLal Shyamindrabhanmsc@gmail.comLal Shyamindrabhanmsc@gmail.com<p>In this paper , nine new Legendre wavelet estimators of functions<br />having bounded third and fourth derivatives have been obtained.These<br />estimators are new and best approximation in wavelet analysis.
