Homotopy Type Theory with (half) 2-adjoint equivalences

2-adjoint equivalences in homotopy type theory

We introduce the notion of (half) 2-adjoint equivalences in homotopy type theory and prove their expected properties.We formalize these results in thelean theorem prover.we introduce the notion of (half) 2-adjoint equivalences in homotopy type theory and prove their expected properties.We formalize these results in thelean theorem prover.
