category theory

is not algebraically coherent

arXiv:2607.28380

summary

The authors prove that the category SKB is not algebraically coherent, which consequently means it is not locally algebraically cartesian closed, and they extend this result to cocommutative Hopf braces.

Abstract

We prove that the category is not algebraically coherent. As a consequence, it is not locally algebraically cartesian closed. Then the same can be deduced for cocommutative Hopf braces.
