On the stable Auslander-Reiten components of certain monomorphism categories

Rasool Hafezi, Yi Zhang

Let be an Artin algebra and let $\rm{Gprj}\mbox{-}Λ$ denote the class of all finitely generated Gorenstein projective -modules. In this paper, we study the components of the…

Mahler discrete residues and summability for rational functions

Carlos E. Arreche, Yi Zhang

We construct Mahler discrete residues for rational functions and show that they comprise a complete obstruction to the Mahler summability problem of deciding whether a given ration…

On some combinatorial sequences associated to invariant theory

Alin Bostan, Jordan Tirrell, Bruce W. Westbury +1

We study the enumerative and analytic properties of some sequences constructed using tensor invariant theory. The octant sequences are constructed from the exceptional Lie group $G…

On sequences associated to the invariant theory of rank two simple Lie algebras

Alin Bostan, Jordan Tirrell, Bruce W. Westbury +1

We study two families of sequences, listed in the On-Line Encyclopedia of Integer Sequences (OEIS), which are associated to invariant theory of Lie algebras. For the first family,…

On (shape-)Wilf-equivalence for words

Ting Guo, Christian Krattenthaler, Yi Zhang

Stankova and West showed that for any non-negative integer and any permutation of there are as many permutations that avoid as there are that avo…
