Computable model theory investigates the algorithmic aspects of model theoretic structures, aiming to delineate the boundaries between the computable and non-computable within various algebraic and ...

In this paper, we characterize (mixtures of) bridges of a continuous time random walk with values in a countable Abelian group. Our main tool is a conditional version of Mecke's formula from the point ...

We show that two abelian-by-finite groups are elementarily equivalent if and only if they satisfy the same sentences with two alternations of quantifiers. We also prove that abelian-by-finite groups ...
