On universal functions in hereditarily finite superstructures
A. N. Khisamiev Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences, Novosibirsk
Abstract:
We obtain the necessary and sufficient condition for the existence of an universal $\Sigma$-function in the hereditarily finite superstructure. We show the application of this criterion to various well-known classes of structures.
Key words:
hereditarily finite superstructure, $\Sigma_{\omega}$-bounded structure, universal $\Sigma$-function, $\Sigma_f$-bounded structure.
