On the bricks (Schur representations) of finite dimensional algebras

Kaveh Mousavand, Charles Paquette

This manuscript treats the diverse applications of bricks within modern representation theory and several related domains, and reviews the recent developments and new results on br…

Galois Coverings, $τ$ -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…

Idempotents in the group algebra of the infinite dihedral group

Ivan Dimitrov, Charles Paquette, David Wehlau +1

We prove that over an algebraically closed field $K$ of characteristic different from $2$ , the group algebra $R = K D_{\infty}$ of the infinite dihedral group $D_\inf…

Almost split sequences and approximations

Shiping Liu, Puiman Ng, Charles Paquette

Let A be an exact category, that is, an extension-closed full subcategory of an abelian category. Firstly, we give some necessary and sufficient conditions for A to have almost spl…
