FRAÏSSÉ LIMITS FOR RELATIONAL METRIC STRUCTURES
Published online by Cambridge University Press: 16 August 2021
Abstract
The general theory developed by Ben Yaacov for metric structures provides Fraïssé limits which are approximately ultrahomogeneous. We show here that this result can be strengthened in the case of relational metric structures. We give an extra condition that guarantees exact ultrahomogenous limits. The condition is quite general. We apply it to stochastic processes, the class of diversities, and its subclass of $L_1$ diversities.
