Cuspidal ribbons provide a sort of comb inatorial bridge between these approaches. I will describe some recent res ults on cuspidal ribbon tableaux\, and some implications in the world of K LR representation theory\, such as bounds on labels of simple factors of S pecht modules\, and the presentation of cuspidal modules. Portions of this talk are joint work with Dina Abbasian\, Lena Difulvio\, Gabrielle Paster nak\, Isabella Sholtes\, and Frances Sinclair.\n LOCATION:https://researchseminars.org/talk/OISTRTS/4/ END:VEVENT END:VCALENDAR
