O‘zbekiston, taraqqiyot yo‘llari, Markaziy Osiyoda ilm-fan va ta’limga, qolaversa, jahon fan va ta’limiga ulkan hissa qo‘shgan olimlar. Shuningdek, "UNIVERSAL JOURNAL OF MATHEMATICAL THEORY AND COMPUTER SCIENCES" ilmiy jurnalining maqsadi ham mazkur yo‘nalishdagi ilmiy-tadqiqot va innovatsiyalarni takomillashtirish muammolari haqida ilmiy jamoatchilikni xabardor qilish, yosh avlodning fan va ta’limga bo‘lgan qiziqishini yanada oshirish, ilmiy qarashlarini bayon etishdan iborat.</p> en-US UNIVERSAL JOURNAL OF MATHEMATICAL THEORY AND COMPUTER SCIENCES https://humoscience.com/index.php/mtcs/article/view/2815 <p>In this paper described some cubic operators which map the n 1– dimensional simplex of idempotent measures to itself. Such operators are divided to two classes: the first class contains all n  n  n  n - matrices with positive entries which for each l th cubic matrix exists number m n l   , where all of the elements of the l th ( l  n) cubic matrix are zeroes except elements as ijml l iml j l p p , , , and mlij l p , ; the second class contains all n  n  n  n - matrices with positive entries which has at least one cubic matrix. These matrices play a role of the stochastic matrices in the case of idempotent measures. For both classes of cubic operators we find fixed points and their characters.</p> Juraev Ilkhomjon Copyright (c) 2024 2024-05-14 2024-05-14 2 12 4 13 https://humoscience.com/index.php/mtcs/article/view/2816 <p>We prove that every local derivation on a complex semisimple finitedimensional Leibniz algebra is a derivation.</p> Юлдашев Иномжон Copyright (c) 2024 2024-05-14 2024-05-14 2 12 14 20
