Fixed Points of Formulas with Double Modalities
S. I. Mardaev Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences, Novosibirsk
Abstract:
In the paper definability of fixed points in modal logics is studied. The following theorem is proved: the least fixed point of the operator $F_\varphi$ in finite transitive model is defined by some iteration of the positive formula $\varphi(p,x_1,\ldots,x_n)$ with double modalities.
