Topic: kripke-joyal semantics solver

GhaS Shee (Mar 17 2021 at 14:52):

I read the part of SGL chapter VI which describes kripke-joyal semantics by example in p.p.310, which states how $U ⊩∀ y ∃ x \alpha (x) = y$ means $\alpha$ is epic in a topos.

Does anyone know a solver which implements this logic ?
