Algebraically closed and existentially closedsubstructures in categorical context

Theory and Applications of Categories, 2004
We investigate categorical versions of algebraically closed (= pure) embeddings, existentially closed embeddings, and the like, in the context of locally presentable categories. The definitions of S.

Existentially Closed Models of Basic Number Theory

1977
This paper is concerned with a subtheory B of (first order) peano number theory P which is strong enough to contain many non-trivial number theoretic facts. We call this theory B basic number theory. Our aim is to give a complete description of the spectrum of (countable) models of B. Of course we will not achieve this aim here, but the results we give

Model theory of Hilbert spaces with a discrete group action

Confluentes Mathematici
In this paper we study expansions of infinite dimensional Hilbert spaces with a unitary representation of a discrete countable group. When the group is finite, we prove the theory of the corresponding expansion, regardless if it is existentially closed,
