Weyl defects in skein theory and quantum cluster charts
Jennifer Brown, Juan Ramón Gómez García, David Jordan +1
We prove a modified invertibility property for the parabolic defects introduced in arXiv:2102.12283, arXiv:2505.14836. Namely, we show that the Borel defect cancels its dual, up to…

Parabolic skein modules
Jennifer Brown, David Jordan
We develop skein theory for 3-manifolds in the presence of codimension-one defects, focusing especially on defects arising from parabolic induction/restriction for quantum groups.…
