# Second cohomology groups of the Hopf$^*$-algebras associated to universal unitary quantum groups

@inproceedings{Das2021SecondCG, title={Second cohomology groups of the Hopf\$^*\$-algebras associated to universal unitary quantum groups}, author={Biswarup Das and Uwe Franz and Anna Kula and Adam G. Skalski}, year={2021} }

We compute the second (and the first) cohomology groups of ∗-algebras associated to the universal quantum unitary groups of not necesarily Kac type, extending our earlier results for the free unitary group U d . The extended setup forces us to use infinitedimensional representations to construct the cocycles.

We show that $A_s(n)$, the coordinate algebra of Wang's quantum permutation group, is Calabi-Yau of dimension $3$ when $n\geq 4$, and compute its Hochschild cohomology with trivial coefficients. We…

We compute the Hochschild and Gerstenhaber-Schack cohomological dimensions of the universal cosovereign Hopf algebras, when the matrix of parameters is a generic asymmetry. Our main tools are…

UNIVERSAL QUANTUM GROUPS

For each invertible m×m matrix Q a compact matrix quantum group Au(Q) is constructed. These quantum groups are shown to be universal in the sense that any compact matrix quantum group is a quantum…

We introduce a non commutative analog of the Bohr compactification. Starting from a general quantum group G we define a compact quantum group bG which has a universal property such as the universal…

Abstract We show that if $A$ and $H$ are Hopf algebras that have equivalent tensor categories of comodules, then one can transport what we call a free Yetter–Drinfeld resolution of the counit of $A$…
