DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ONCAS/1/">Un
 iversal Quantum Semigrupoids</a>\nby Chelsea Walton (Rice University\, USA
 ) as part of ONCAS Online Noncommutative Algebra Seminar\n\n\nAbstract\nIn
  a recent paper (https://arxiv.org/abs/2008.00606)\, Hongdi Huang\, Elizab
 eth Wicks\, Robert Won\, and I introduce the concept of a universal quantu
 m linear semigroupoid (UQSGd). This is a weak bialgebra that coacts on a (
 not necessarily connected) graded algebra A. Our main result is that when 
 A is the path algebra kQ of a finite quiver Q each of the various UQSGds i
 ntroduced in our work is isomorphic to the face algebra attached to Q (an 
 important weak bialgebra due to Hayashi). Most of the talk will be dedicat
 ed to setting up context and terminology towards the main result.\n
