A basic algebra is of finite representation type if there are only finitely many non-isomorphic indecomposable representations. Basi c Hopf algebras of finite representation type have been classified by Liu and Li in 2004. As algebras\, they are just copies of Nakayama algebras. A pointed coalgebra is of discrete co-representation type\, if there are on ly finitely many non-isomorphic indecomposable co-representations for each dimension vector. We are trying to classify pointed Hopf algebras of dis crete co-representation type. We first classify their Ext-quivers as coalg ebras. Then we compute their algebra structures for each case. This is a j oint work with Miodrag Iovanov\, Emre Sen and Alexander Sistko.\n LOCATION:https://researchseminars.org/talk/GASC/8/ END:VEVENT END:VCALENDAR
