Avalanche homology of digraphs via sandpile dynamics

Henri RiihimÃ¤ki, Jason P. Smith

We introduce avalanche homology as a new (di)graph homology theory, based on the dynamics of the sandpile model. Avalanche homology is the simplicial homology of the avalanche comp…

Representation Cohomology of a Small Category

Markus Klemetti, Ran Levi, Henri Riihimaki +1

Let $C_{∙}$ be a simplicial object in the category $C a t$ of small categories. For a field $k$ , taking the Grothendieck groups of isomorphism classes of $k C_{n}$ -modules gives ris…

Foundations of Differential Calculus for modules over posets

Jacek Brodzki, Ran Levi, Henri RiihimÃ¤ki

Let $k$ be a field and let $C$ be a small category. A $k$ -linear representation of $C$ , or a $k C$ -module, is a functor from $C$ to the category of finite dimensional vector spaces…
