Center node: "extended initiality for typed abstract syntax"
  Abstract: Initial Semantics aims at interpreting the syntax associated to a signature#N#as the initial object of some category of 'models', yielding induction and#N#recursion principles for abstract syntax. Zsid\'o proves an initiality result#N#for simply-typed syntax: given a signature S, the abstract syntax associated to#N#S constitutes the initial object in a category of models of S in monads.#N#However, the iteration principle her theorem provides only accounts for#N#translations between two languages over a fixed set of object types. We#N#generalize Zsid\'o's notion of model such that object types may vary, yielding#N#a larger category, while preserving initiality of the syntax therein. Thus we#N#obtain an extended initiality theorem for typed abstract syntax, in which#N#translations between terms over different types can be specified via the#N#associated category-theoretic iteration operator as an initial morphism. Our#N#definitions ensure that translations specified via initiality are type-safe,#N#i.e. compatible with the typing in the source and target language in the#N#obvious sense. Our main example is given via the propositions-as-types#N#paradigm: we specify propositions and inference rules of classical and#N#intuitionistic propositional logics through their respective typed signatures.#N#Afterwards we use the category--theoretic iteration operator to specify a#N#double negation translation from the former to the latter. A second example is#N#given by the signature of PCF. For this particular case, we formalize the#N#theorem in the proof assistant Coq. Afterwards we specify, via the#N#category-theoretic iteration operator, translations from PCF to the untyped#N#lambda calculus.
