natural deduction metalanguage, practical foundations
type theory (dependent, intensional, observational type theory, homotopy type theory)
computational trinitarianism =
propositions as types +programs as proofs +relation type theory/category theory
abstract duality: opposite category,
concrete duality: dual object, dualizable object, fully dualizable object, dualizing object
Examples
between higher geometry/higher algebra
Langlands duality, geometric Langlands duality, quantum geometric Langlands duality
In QFT and String theory
Adjoint logic or adjoint type theory is formal logic or type theory which natively expresses adjunctions of modal operators, adjoint modalities.

A framework for (homotopy-)type theoretic adjoint logic (modal type theory) is discussed, in various stages of generality, in
