On Semisimple Proto-Abelian Categories Associated to Inverse Monoids
Alexander Sistko
Let be a finite abelian group written multiplicatively, with the pointed abelian group formed by adjoining an absorbing element . There is an assoc…
On the Combinatorics of -Representations of Pseudotree Quivers
Jaiung Jun, Jaehoon Kim, Alex Sistko
We investigate quiver representations over . Coefficient quivers are combinatorial gadgets equivalent to -representations of quivers. We focus on the ca…
Pointed Hopf Algebras of Discrete Corepresentation Type
Miodrag Iovanov, Emre Sen, Alexander Sistko +1
We classify pointed Hopf algebras of discrete corepresentation type over an algebraically closed field K with characteristic zero. For such algebras , we explicitly determine th…
Coefficient Quivers, -Representations, and Euler Characteristics of Quiver Grassmannians
Jaiung Jun, Alex Sistko
A quiver representation assigns a vector space to each vertex, and a linear map to each arrow. When one considers the category of vector spaces ``over…
On quiver representations over
Jaiung Jun, Alex Sistko
We study the category of representations of a quiver over "the field with one element", denoted by , and the Hall algebra of $\text…
