On Nijenhuis Lie triple systems

Shuangjian Guo, Bibhash Mondal, Ripan Saha

In this paper, we investigate the mathematical structure of Nijenhuis Lie triple systems, an extension of classical Lie triple systems augmented with the Nijenhuis operator. Our st…

Deformation cohomology of morphisms of Lie-Yamaguti algebras

Bibhash Mondal, Ripan Saha

We study cohomology of morphisms of Lie-Yamaguti algebras. As an application, we establish that this cohomology `controls' the formal deformations. Additionally, we demonstrate its…

Nijenhuis operators on Leibniz algebras

Bibhash Mondal, Ripan Saha

In this paper, we study Nijenhuis operators on Leibniz algebras. We discuss the relationship of Nijenhuis operators with Rota-Baxter operators and modified Rota-Baxter operators on…

On compatible Leibniz algebras

Abdenacer Makhlouf, Ripan Saha

In this paper, we study compatible Leibniz algebras. We characterize compatible Leibniz algebras in terms of Maurer-Cartan elements of a suitable differential graded Lie algebra. W…

Cohomology of modified Rota-Baxter Leibniz algebra of weight

Bibhash Mondal, Ripan Saha

Rota-Baxter operators have been paid much attention in the last few decades as they have many applications in mathematics and physics. In this paper, our object of study is modifie…

On deformation cohomology of compatible Hom-associative algebras

Taoufik Chtioui, Ripan Saha

In this paper, we consider compatible Hom-associative algebras as a twisted version of compatible associative algebras. Compatible Hom-associative algebras are characterized as Mau…

A Fractional Image Inpainting Model Using a Variant of Mumford-Shah Model

Abdul Halim, Abdur Rohim, B. V. Rathish Kumar +1

In this paper, we propose a fourth order PDE model for image inpainting based on a variant of the famous Mumford-Shah (MS) image segmentation model. Convexity splitting is used to…

On equivariant Lie-Yamaguti algebras and related structures

Shuangjian Guo, Bibhash Mondal, Ripan Saha

In this paper, we first discuss cohomology and a one-parameter formal deformation theory of Lie-Yamaguti algebras. Next, we study finite group actions on Lie-Yamaguti algebras and…

On 3-Lie algebras with a derivation

Shuangjian Guo, Ripan Saha

In this paper, we study 3-Lie algebras with derivations. We call the pair consisting of a 3-Lie algebra and a distinguished derivation by the 3-LieDer pair. We define a cohomology…

Rota-Baxter operators and related structures on anti-flexible algebras

Shuangjian Guo, Ripan Saha

In this paper, we first construct a graded Lie algebra which characterizes Rota-Baxter operators on an anti-flexible algebra as Maurer-Cartan elements. Next, we study infinitesimal…

On -type (equivariant) cohomology of Hom-pre-Lie algebras

Shuangjian Guo, Ripan Saha

In this paper, we define a new cohomology theory for multiplicative Hom-pre-Lie algebras which controls deformations of Hom-pre-Lie algebra structure. This new cohomology is a natu…

Involutive and oriented dendriform algebras

Apurba Das, Ripan Saha

Dendriform algebras are certain splitting of associative algebras and arise naturally from Rota-Baxter operators, shuffle algebras and planar binary trees. In this paper, we first…

On certain classes of algebras in which centralizers are ideals

Ripan Saha, David A. Towers

This paper is primarily concerned with studying finite-dimensional anti-commutative nonassociative algebras in which every centralizer is an ideal. These are shown to be anti-assoc…

On equivariant dendriform algebras

Apurba Das, Ripan Saha

Dendriform algebras are certain associative algebras whose product splits into two binary operations and the associativity splits into three new identities. In this paper, we study…

Equivariant one-parameter formal deformations of Hom-Leibniz algebras

Goutam Mukherjee, Ripan Saha

Aim of this paper is to define a new type of cohomology for multiplicative Hom-Leibniz algebras which controls deformations of Hom-Leibniz algebra structure. The cohomology and the…
