We prove that is possible to extend Girard's Ludics so as to have repetitions (hence exponentials), and still have the results on semantical types which characterize Ludics in the panorama of Gameâ€¦ (More)

In this paper, we use Girardâ€™s Ludics to analyze focalization, a fundamental property of linear logic. In particular, we show how this can be realized interactively thanks to section-retraction pairsâ€¦ (More)

Focalization property is a deep outcome of linear logic proof theory, putting to the foreground the role of polarity in logic. It resulted an important advances in various fields, ranging from linearâ€¦ (More)

Traditional GÃ¶del completeness holds between finite proofs and infinite models over formulas of finite depth, where proofs and models are heterogeneous. Our purpose is to provide an interactive formâ€¦ (More)

In this paper, we present an interactive semantics for derivations in an infinitary extension of classical logic. The formulas of our language are possibly infinitary trees labeled by propositionalâ€¦ (More)

An orthodox introduction of a paper on ludics should begin as follows. First, the authors say what ludics is commonly intended to be: typically, they would say that it is a kind of game semanticsâ€¦ (More)
