Novel non‐involutive solutions of the Yang–Baxter equation from (skew) braces

open access: yesJournal of the London Mathematical Society, Volume 110, Issue 4, October 2024.
Abstract We produce novel non‐involutive solutions of the Yang–Baxter equation coming from (skew) braces. These solutions are generalisations of the known ones coming from braces and skew braces, and surprisingly in the case of braces, they are not necessarily involutive.

Manin Triples and Bialgebras of Left-Alia Algebras Associated with Invariant Theory

open access: yesMathematics
A left-Alia algebra is a vector space together with a bilinear map satisfying the symmetric Jacobi identity. Motivated by invariant theory, we first construct a class of left-Alia algebras induced by twisted derivations. Then, we introduce the notions of

Near braces and p$p$‐deformed braided groups

open access: yesBulletin of the London Mathematical Society, Volume 56, Issue 1, Page 124-139, January 2024.
Abstract Motivated by recent findings on the derivation of parametric noninvolutive solutions of the Yang–Baxter equation, we reconstruct the underlying algebraic structures, called near braces. Using the notion of the near braces we produce new multi‐parametric, nondegenerate, noninvolutive solutions of the set‐theoretic Yang–Baxter equation.

Bialgebraic Structures And Smarandache Bialgebraic Structures

open access: yes, 2003
The study of bialgebraic structures started very recently. Till date there are no books solely dealing with bistructures. The study of bigroups was carried out in 1994-1996. Further research on bigroups and fuzzy bigroups was published in 1998. In the year 1999, bivector spaces was introduced.

Equivariant resolutions over Veronese rings

open access: yesJournal of the London Mathematical Society, Volume 109, Issue 1, January 2024.
Abstract Working in a polynomial ring S=k[x1,…,xn]$S={\mathbf {k}}[x_1,\ldots ,x_n]$, where k${\mathbf {k}}$ is an arbitrary commutative ring with 1, we consider the d$d$th Veronese subalgebras R=S(d)$R={S^{(d)}}$, as well as natural R$R$‐submodules M=S(⩾r,d)$M={S^{({\geqslant r},{d})}}$ inside S$S$.

Differential Antisymmetric Infinitesimal Bialgebras, Coherent Derivations and Poisson Bialgebras

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2023
We establish a bialgebra theory for differential algebras, called differential antisymmetric infinitesimal (ASI) bialgebras by generalizing the study of ASI bialgebras to the context of differential algebras, in which the derivations play an important role.

Adjunctions Between Hom and Tensor as Endofunctors of (bi-)Module Category of Comodule Algebras Over a Quasi-Hopf Algebra

open access: yesپژوهش‌های ریاضی, 2020
Introduction Over a commutative ring k, it is well known from the classical module theory that the tensor-endofunctor of is left adjoint to the Hom-endofunctor. The unit and counit of this adjunction is obtained trivially.

Lie bialgebras constructed from Zinbiel bialgebras and Leibniz bialgebras

open access: yes
There is a Lie algebra structure on the tensor product of a Leibniz algebra and a Zinbiel algebra for the operads of Leibniz algebras and Zinbiel algebras are Koszul dual. In this paper, we extend such conclusion to the context of bialgebras. We show that there is a Lie bialgebra structure on the tensor product of a Leibniz bialgebra and a quadratic ...

Preantipodes for dual quasi-bialgebras [PDF]

open access: yesIsrael Journal of Mathematics, 2012
It is known that a dual quasi-bialgebra with antipode $H$, i.e. a dual quasi-Hopf algebra, fulfils a fundamental theorem for right dual quasi-Hopf $H$-bicomodules. The converse in general is not true. We prove that, for a dual quasi-bialgebra $H$, the structure theorem amounts to the existence of a suitable map $S:H\rightarrow H$ that we call a ...

Small bialgebras with a projection

open access: yesJournal of Algebra, 2007
Let \(A\) be a bialgebra over a field \(K\) of characteristic zero, \(H\) a subbialgebra with antipode, such that there is a coalgebra projection \(p\) of \(A\) onto \(H\). Let \(R\) be the \(H\)-coinvariant part of \(A\), i.e., the elements \(a\) in \(A\) so that \(\sum a_1\otimes p(a_2)=a\otimes 1\). The authors determine the structure of \(A\) when \
