Recognizing CGW categories among pointed stable double Segal spaces
arXiv:2607.12327
summary
The paper proves that any CGW category can be interpreted as a pointed stable double Segal space and gives a classifying diagram construction that identifies the two structures, clarifying their relationship for algebraic K‑theory.
Abstract
In this paper, we establish a precise relationship between CGW categories and pointed stable double Segal spaces, both of which were developed as general input for algebraic K-theory. In particular, we show that any CGW category can be regarded as a pointed stable double Segal space, and they can be identified using a classifying diagram construction for double categories with shared isomorphisms.
