Efimov K-theory and universal localizing invariant
arXiv:2302.13052
Abstract
We give some basic properties of Efimov K-theory. In particular, Efimov K-theory is corepresentable, lax symmetric monoidal functor, preserves any small products and sends Milnor squares satisfying base change to cartesian squares.
There are some errors and inappropriate writings. Thm 4.16 and don't work well for additive invariants
