Generalized permutation matrices and non-weight modules over $sl (m ∣1)$

Ivan Dimitrov, Khoa Nguyen, Charles Paquette +1

We study the category $M_{sl (m ∣1)} (k ∣ k)$ of $U (h) -free$ $U (sl (m ∣1))$ -modules of rank $k$ in each parity (rank $(k…

Inversion Sets and Quotient Root Systems

Ivan Dimitrov, Cole Gigliotti, Etan Ossip +2

The main result of this paper is a recursive description of all decompositions \[ Î^+ = Î¦_1 \sqcup Î¦_2 \sqcup \dots \sqcup Î¦_k \] of the positive roots $I^^{+}$ of an arbitrary r…

Galois Coverings, $I ¨ $ -Rigidity and Mutations

Charles Paquette, Deepanshu Prasad, David Wehlau

For an algebraically closed field $K$ , we consider a Galois $G$ -covering $B \to A$ between locally bounded $K$ -categories given by bound quive…
