Sheaf Subcategories of Quiver Representations
Eric M. Schmid, Fernando Tohmé, William Chin
Let be a finite quiver without oriented cycles, its path category, and a field. This paper is expository. We assemble in one place, and in elementary combinatorial form…
The classification of generalized Riemann derivatives
J. Marshall Ash, Stefan Catoiu, William Chin
We characterize all pairs , of generalized Riemann differences for which -differentiability implies -differentiability. Two ge…
Coverings of graded pointed Hopf algebras
William Chin, Esther Beneish
We introduce the concept of a covering of a graded pointed Hopf algebra. The theory developed shows that coverings of a bosonized Nichols algebra can be concretely expressed by bip…
The translation operator for self-projective coalgebras
William Chin
We describe the transpose operator for self-projective and symmetric coalgebras in terms of the syzygy and Nakayama functors.
Galois coverings of pointed coalgebras
William Chin
We introduce the concept of a Galois covering of a pointed coalgebra. The theory developed shows that Galois coverings of pointed coalgebras can be concretely expressed by smash co…
Coxeter transformation and inverses of Cartan matrices for coalgebras
William Chin, Daniel Simson
Let C be a coalgebra and consider the Grothendieck groups of the categories of the socle-finite injective right and left C-comodules. One of the main aims of the paper is to study…
