DESCRIPTION:This workshop is an informal gathering
of people that study universal models or use them
in their research. There will be presentations bo
th on finished studies and on work in progress. Un
iversal models were originated by V. Shethman and
V. Rybakov, anticipated by D. de Jongh's dissertat
ion in 1968. In intuitionistic logic the subject r
eemerged in N. Bezhanishvili's dissertation in 200
6. The logics involved today comprise intuitionist
ic propositional logic and modal logics. In intuit
ionistic logic one has finite universal models for
some fragments missing some of the usual connecti
ves, and the usual complicated infinite ones for t
he full logic. One of the modal logics that will b
e presented is GLP, an extension of Gödel-Löb's lo
gics GL that has a different provability modality
for each ordinal. Another modal logic that will be
discussed is S4. At the workshop the subject will
be approached from the algebraic/co-algebraic sid
e as well. For more information, see http://www.i
