DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ONCAS/2/">Bi
 separable extensions are not necessarily Frobenius</a>\nby José Gómez To
 rrecillas (Universidad de Granada\, Spain) as part of ONCAS Online Noncomm
 utative Algebra Seminar\n\n\nAbstract\nNecessary and sufficient conditions
  are given on an Ore extension A[x\; σ\, δ]\, where A is a finite dimens
 ional algebra over a field F\, for being a Frobenius extension of the ring
  of commutative polynomials F[x]. As a consequence\, as the title of this 
 talk highlights\, we provide a negative answer to a problem stated by Caen
 epeel and Kadison. The involved ring-theoretical notions will be also disc
 ussed.  \n\n\nThe talk is based on the joint paper with F.J. Lobillo\, G. 
 Navarro and P. Sánchez-Hernández\n
