Some categorical remarks on coarse subspaces of coarse spaces
Muneto Miyaji, Hiroaki Nagaya, Kento Ogawa +1
In this paper, we provide a categorical framework for understanding coarse subspaces of coarse spaces. First, we introduce the notion of a controlled total relation between coarse…
A proof of Kobayashi's properness criterion from a viewpoint of metric geometry
Kento Ogawa, Takayuki Okuda
Let be a locally-compact group and a pair of closed subgroups of . For the cases where is a real linear reductive Lie group, T. Kobayashi [Math. Ann. '89, J. Lie…
Wreath products and projective system of non Schurian association schemes
Makoto Matsumoto, Kento Ogawa
A wreath product is a method to construct an association scheme from two association schemes. We determine the automorphism group of a wreath product. We show a known result that a…
Functoriality of Bose-Mesner algebras and profinite association schemes
Makoto Matsumoto, Kento Ogawa, Takayuki Okuda
We show that taking the set of primitive idempotents of commutative association schemes is a functor from the category of commutative association schemes with surjective morphisms…
