In this paper I raise questions about the predicate restriction, which claims that only stage-level predicates may appear in coda of an existential sentence. present novel data from Mandarin to show restriction is not universal: It systematically absent Mandarin. propose reason behind its absence syntactic. Specifically, English cannot be as large a TP, while contains full TP. This, combination...

Abstract Predicate intuitionistic logic is a well-established fragment of dependent types. Proof construction in this logic, as the Curry–Howard isomorphism states, process program synthesis. We present automata that can handle proof and synthesis full first-order logic. Given formula, we construct an automaton such formula provable if only has accepting run. As further research, makes it possi...
