Universal functions and $k\sigma$-structures
A. N. Khisamiev Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences, Novosibirsk
Abstract:
We introduce the concept of $K\Sigma$-structure and prove the existence of a universal $\Sigma$-function in the hereditarily finite superstructure over this structure. We exhibit some examples of families of $K\Sigma$-structures of the theory of trees.
Keywords:
hereditarily finite superstructure, universal $\Sigma$-function, $K\Sigma$-structure, tree.
