2329. Jaruwat Rodbanjong and Athipat Thamrongthanyalak Definable version of Wedderburn-Artin Theorem in o-minimal structures E-mail: , Submission date: 24 January 2023 Abstract: Here we work in an arbitrary (but fixed) o-minimal expansion of a dense linearly ordered set. We say that a definable ring is definably semiprime if squares of nontrivial two-sided ideals definable in the expansion are non-trivial. We prove a definable version of Wedderburn-Artin Theorem and give a characterization of definably semiprime rings.
