Proofs in Ludics, have an interpretation provided by their
, that is the objects they interact with. We shall follow the same idea by proposing that sentence meanings are given by the
they are opposed to in a dialectical interaction. In this aim, we shall develop many concepts of Ludics like
(which generalize proofs),
(that is sets of designs which are equal to their bi-orthogonal). Behaviours give statements their interactive meaning. Such a conception may be viewed at the intersection between
accounts of semantics, but it enlarges them by allowing to deal with possibly infinite processes instead of getting stuck to an atomic level when decomposing a formula.
