| dc.description | We give a description in terms of square matrices of the family of group-like algebras with $S*id=id*S=uε$. In the case that $S=id$ and $char\Bbbk$ is not 2 and does not divide the dimension of the algebra, this translation take us to Hadamard matrices and, particularly, to examples of biFrobenius algebras satisfying $S*id=id*S=uε$ and that are not Hopf algebras. Finally, we generalize some known results on separability and coseparability valid for finite dimensional Hopf algebras to this special class of biFrobenius algebras with $S*id=id*S=uε$, presenting a version of Maschke's theorem for this family. | |
