Summary

This talk, presented by Oghenetega Ighedo at the OAL-RAG 2024 conference, focuses on the torsion ideal of a ring homomorphism. The speaker begins by recalling the definition of the torsion ideal introduced by Dobbs and Picavet, which involves non-zerodivisors. He then generalizes this concept by replacing the zero ideal with the nilradical, defining the nil-torsion ideal. The talk explores the relationship between these ideals, showing that while the torsion ideal is always a radical ideal, the nil-torsion ideal is not necessarily so. The speaker also introduces a frame-theoretic analogue of the torsion ideal for algebraic frames with the finite intersection property, specifically in the context of radical ideals and z-ideals. Key results include a characterization of the torsion ideal in terms of units in the frame of radical ideals, and a comparison of the torsion and nil-torsion ideals under certain conditions, such as reducedness and condition C. The talk concludes with a discussion of z-ideals, where the speaker introduces the concept of nearly semi-primitive rings and presents analogous results for the frame of z-ideals.
