The dynamical Cuntz semigroup and ideal-free quotients of Cuntz semigroups
Joan Bosa, Francesc Perera, Jianchao Wu +1
We develop a theory of general quotients for W- and Cu-semigroups beyond the case of quotients by ideals. To this end, we introduce the notion of a normal pair, which allows us to…

Isomorphism of the cubical and categorical cohomology groups of a higher-rank graph
Elizabeth Gillaspy, Jianchao Wu
We use category-theoretic techniques to provide two proofs showing that for a higher-rank graph , its cubical (co-)homology and categorical (co-)homology groups are isomorphic i…
