Let H be a Hopf algebra that is $\mathbb Z$ ℤ -graded as an algebra. We provide sufficient conditions for a 2-cocycle twist of H to be a Zhang twist of H. In particular, we introduce the notion of a twisting pair for H such that the Zhang twist of H by such a pair is a 2-cocycle twist. We use twisting pairs to describe twists of Manin’s universal quantum groups associated with quadratic algebras and provide twisting of solutions to the quantum Yang-Baxter equation via the Faddeev-Reshetikhin… 

A cogroupoid associated to preregular forms

We construct a cogroupoid given by preregular forms. This yields a Morita-Takeuchi equivalence between Manin’s universal quantum groups associated to superpotential algebras.

A Primer on Twists in the Noncommutative Realm focusing on Algebra, Representation Theory, and Geometry

. We review several techniques that twist an algebra’s multiplica- tive structure. We first consider twists by an automorphism, also known as Zhang twists, and we relate them to 2-cocycle twists of

Twisting Manin's universal quantum groups and comodule algebras

. Let H be a Hopf algebra and σ be a 2-cocycle on H . Using the tensor equivalence between the comodule categories of H and of its 2-cocycle twist H σ , we study twists of superpotentials, comodule



Twisted Graded Algebras and Equivalences of Graded Categories

Let A = 0n S,o-^n be a connected graded /r-algebra and let Gr-A denote the category of graded right /4-modules with morphisms being graded homomorphisms of degree 0. If {r,,| n e 1} is a set of

We prove that, in case $A(c)$ = the FRT construction of a braided vector space $(V,c)$ admits a weakly Frobenius algebra $\mathfrak B$ (e.g. if the braiding is rigid and its Nichols algebra is finite

Free Hopf algebras generated by coalgebras

If $H$ is a commutative or cocommutative Hopf algebras over a field $k$ , it is well known that the antipode of $H$ is of order 2. If $H$ is a finite dimensional Hopf algebra over $k$ , then the
