We investigate relations between the properties of an algebra and its varieties of finite-dimensional module structures, on the example of the Jordan plane R = k〈x, y〉/(xy − yx− y). Complete description of irreducible components of the representation variety mod(R,n) obtained for any dimension n, it is shown that the variety is equidimensional. The influence of the property of the non-commutati...

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...

In this paper, we prove the generalized Kaplansky conjecture for Jordan algebras of type Jn, in particular self-adjoint 2 × matrices over R, C, H, and O. fact, that image multilinear polynomial must be either {0}, space V pure elements, or Jn.

Let G be a simple connected graph. The generalized polarity Wiener index of G is defined as the number of unordered pairs of vertices of G whose distance is k. Some formulas are obtained for computing the generalized polarity Wiener index of the Cartesian product and the tensor product of graphs in this article.
