English abstract:
Hypersequent calculi arise by generalizing standard sequent calculi
to refer to whole contexts of sequents instead of single sequents.
We present a number of results using hypersequents to obtain
a Gentzen-style characterization for the family of Gödel logics.
We first describe analytic calculi for propositional finite and infinite-valued
Gödel logics. We then show that the framework of hypersequents allows one to move straightforwardly
from the propositional level to first-order as well as propositional
quantification. A certain type of modalities, enhancing the expressive power of
Gödel logic, is also considered.
