Games and Elementary Equivalence of Ii1 Factors
We use Ehrenfeucht-Fräıssé games to give a local geometric criterion for elementary equivalence of II1 factors. We obtain as a corollary that two II1 factors are elementarily equivalent if and only their unitary groups are elementarily equivalent as Z4-metric spaces.

متن کاملForm Factors of the Elementary Field in the Bullough - Dodd
We derive the recursive equations for the form factors of the local hermitian operators in the Bullough-Dodd model. At the self-dual point of the theory, the form factors of the fundamental field of the Bullough-Dodd model are equal to those of the fundamental field of the Sinh-Gordon model at a specific value of the coupling constant. 1 The Bullough-Dodd Model The Bullough-Dodd (BD) model [1, ...
