Classifying bicrossed products of Hopf algebras
Let A and H be two Hopf algebras. We shall classify up to an isomorphism that stabilizes A
all Hopf algebras E that factorize through A and H by a cohomological type object …

A 4-Sphere With Noncentral Radius and its Instanton Sheaf
LS Cirio, C Pagani - Letters in Mathematical Physics, 2015 - Springer
Abstract We build an SU (2)-Hopf bundle over a quantum toric four-sphere whose radius is
noncentral. The construction is carried out using local methods in terms of sheaves of Hopf …
