in this paper, we give a characterization of strongly jordan zero-product preserving maps on normed algebras as a generalization of  jordan zero-product preserving maps. in this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly jordan zero-product preserving maps are completely different. also, we prove that the direct p...

یک نگاشت خطی t از یک جبر باناخ َ به جبر باناخ إ حافظ حاصلضرب صفر است هرگاه برای هر a,b در a بافرض ab=0 داشته باشیم t(a)t(b)=0 . هدف این پایان نامه بررسی این پرسش است که آیا هر نگاشت پوشا و پیوسته حافظ حاصلضرب صفر یک همریختی وزن دار است؟ نشان میدهیم که پاسخ این سئوال در مورد کلاس بزرگی از جبرهای باناخ شامل جبرهای گروهی مثبت است. روش ما شامل در نظر گرفتن یک نگاشت دو خطی ? از a×a به توی x است(برا...

The notion of strongly Lie zero-product preserving maps on normed algebras as a generalization of Lie zero-product preserving maps are dened. We give a necessary and sufficient condition from which a linear map between normed algebras to be strongly Lie zero-product preserving. Also some hereditary properties of strongly Lie zero-product preserving maps are presented. Finally the second dual of...

We say that an algebra is zero-product balanced if ab⊗c and a⊗bc agree modulo tensors of elements with zero-product. This closely related to but more general than the notion a determined introduced developed by Brešar, Villena others. Every surjective, preserving map from automatically weighted epimorphism, this implies algebras are their linear structure. Further, commutator subspace can be de...

‎Let $R$ be commutative ring with identity and $M$ be an $R$-module‎. ‎The zero divisor graph of $M$ is denoted $Gamma{(M)}$‎. ‎In this study‎, ‎we are going to generalize the zero divisor graph $Gamma(M)$ to submodule-based zero divisor graph $Gamma(M‎, ‎N)$ by replacing elements whose product is zero with elements whose product is in some submodules $N$ of $M$‎. ‎The main objective of this pa...
