## Summary - Introduce a general naming scheme for infix endooperations on propositions and the corresponding endooperations on types - Remove uses of `∀` - remove the redundant `implication-Prop` - Add table for propositional logic - Add table for operations on propositions - Correct the definition of exclusive disjunction. It is now named "exclusive sum" (up for discussion) - Introduce _disjunction_, (the correct definition of) _exclusive disjunction_, and _mere logical equivalence_ of types - Introduce _coinhabitedness_ of types - Introduce universal quantification - Define the homotopy preorder of types - Prove that existential quantification of type families agrees with existential quantification of the propositional reflection of the type family - Prove that disjunction of types agree with disjunction of the propositional reflections of the summands Intersects with #1060. Resolves #984. --------- Co-authored-by: Egbert Rijke <[email protected]>
