Smoothness of commutative Hopf algebras
Kensuke Egami, Akira Masuoka, Kenta Suzuki
Hopf algebras, most generally in a semisimple abelian symmetric monoidal category, are here supposed to be commutative but not to be of finite-type, and their (equivariant) smoothn…

Torsors in super-symmetry
Akira Masuoka, Takuya Oe, Yuta Takahashi
Torsors under affine groups are generalized in the super context by super-torsors under affine super-groups. We investigate those super-torsors by using Hopf-algebra language and t…
