On complements and the factorization problem of Hopf algebras

Sebastian Burciu (2011)

Open Mathematics

Similarity:

Two new results concerning complements in a semisimple Hopf algebra are proved. They extend some well-known results from group theory. The uniqueness of a Krull-Schmidt-Remak type decomposition is proved for semisimple completely reducible Hopf algebras.

Multiplier Hopf algebroids arising from weak multiplier Hopf algebras

Thomas Timmermann, Alfons Van Daele (2015)

Banach Center Publications

Similarity:

It is well-known that any weak Hopf algebra gives rise to a Hopf algebroid. Moreover it is possible to characterize those Hopf algebroids that arise in this way. Recently, the notion of a weak Hopf algebra has been extended to the case of algebras without identity. This led to the theory of weak multiplier Hopf algebras. Similarly also the theory of Hopf algebroids was recently developed for algebras without identity. They are called multiplier Hopf algebroids. Then...
