Cohomologies of Reynolds Lie algebras with derivations and its applications

The aim of this paper is to study the cohomology theory of Reynolds Lie algebras equipped with derivations and to explore related applications. We begin by introducing the concept of Reynolds LieDer pairs. Subsequently, we construct the associated cohomology. Finally, we investigate formal deformations, abelian extensions, and extensions of a pair of derivations, all interpreted through the lens of cohomology groups.

Maurer-Cartan characterization and cohomology of compatible LieDer and AssDer pairs

A LieDer pair (respectively, an AssDer pair) is a Lie algebra equipped with a derivation (respectively, an associative algebra equipped with a derivation). A couple of LieDer pair structures on a vector space are called Compatible LieDer pairs (respectively, compatible AssDer pairs) if any linear combination of the underlying structure maps is still a LieDer pair (respectively, AssDer pair) structure. In this paper, we study compatible AssDer pairs, compatible LieDer pairs, and their cohomologies. We also discuss about other compatible structures such as compatible dendriform algebras with derivations, compatible zinbiel algebras with derivations, and compatible pre-LieDer pairs. We describe a relationship amongst these compatible structures using specific tools like Rota-Baxter operators, endomorphism operators, and the commutator bracket.

Cohomologies and deformations of weighted Rota-Baxter Lie algebras and associative algebras with derivations

The purpose of the present paper is to investigate cohomologies and deformations of weighted Rota-Baxter Lie algebras as well as weighted Rota-Baxter associative algebras with derivations. First we introduce a notion of weighted Rota-Baxter LieDer and weighted Rota-Baxter AssDer pairs. Then we construct cohomologies of weighted Rota-Baxter LieDer pairs, weighted Rota-Baxter AssDer pairs and we discuss the relation between their cohmologies. Finally, as an application, we study deformations of both of them.

On compatible Lie and pre-Lie Yamaguti algebras

This study aims to generalize the notion of compatible Lie algebras to the compatible Lie Yamaguti algebras. Along with describing the representation of the compatible Lie Yamaguti algebra in detail, we also introduce the Maurer-Cartan characterization and cohomology of Lie Yamaguti algebras. As a result of the obtained cohomology, we studied its deformation. We define Rota-Baxter operators on compatible Lie Yamaguti algebras as well as on compatible pre-Lie Yamaguti algebras. Using Rota-Baxter operators, we examine how compatible Lie (and compatible pre-Lie) Yamaguti algebras are related.

On the Hom-Lie CoDer pairs

The present research paper investigates the intricate fields of Hom-Lie algebra and Hom-Lie coalgebra, providing a complete analysis of their key concepts and important examples. Precisely, the paper introduces the concept of Hom-Lie coderivation pairs and demystifies its duality with Hom-Lie derivation pairs, inspecting pertinent facts such as representation and semi-direct product. Furthermore, the study examines the connection between Hom-Lie, pre-Lie, and Ass-Coder pairs with the use of crucial operators such as commutator, Rota-Baxter operator, and endomorphism operator. Finally, the paper concludes by presenting the construction of Hom-pre-Lie coderivation pairs through a dual to an endomorphism operator.
