The Gray Product of $(\infty, n)$ -Categories via Lax Grids

Shai Keidar, Leor Neuhauser

We introduce a new model for $(\infty, n)$ -categories as Segal sheaves on lax grids, which are pasting diagrams of lax cubes. This model allows for a direct construction of the Gray…

Rigid Algebras and Cospans

Leor Neuhauser

We introduce rigid algebras, a generalization of rigid categories to arbitrary symmetric monoidal $(\infty, 2)$ -categories. We develop their general theory, showing in particular th…

Existentially closed models of fields with a distinguished submodule

Christian d'Elbée, Itay Kaplan, Leor Neuhauser

This paper deals with the class of existentially closed models of fields with a distinguished submodule (over a fixed subring). In the positive characteristic case, this class is e…
