Abstract
We study $$P^{*}$$ -combinations of almost $$\omega$$ -categorical weakly o-minimal theories. One of natural questions in the study of such a combination is the question of preserving or weakening certain properties of initial theories. Earlier, criteria for Ehrenfeuchtness of $$P^{*}$$ -combinations of countably many $$\omega$$ -categorical ordered theories were obtained. Here we prove that if a $$P^{*}$$ -combination of countably many models of almost $$\omega$$ -categorical weakly o-minimal theories preserves weak o-minimality then it also preserves almost $$\omega$$ -categoricity.
