DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OISTRTS/28/"
 >(Some) Gram Determinants for \\(A_n\\) nets</a>\nby Robert Spencer (Unive
 rsity of Cambridge) as part of OIST representation theory seminar\n\n\nAbs
 tract\nThe nets giving a diagrammatic description of the category of (tens
 or products of) fundamental representations of \\(sl_n\\) form a cellular 
 category. We can then ask about the natural inner form on certain cell mod
 ules. In this talk\, we will calculate the determinant of some of these fo
 rms in terms of certain traces of clasps or magic weave elements (for whic
 h there is a conjectured formula due to Elias). The method appears moderat
 ely general and gives a result which is hopefully illuminating and applica
 ble to other monoidal\, cellular categories.\n
