Abstract: We will start with a survey of the (in)decomposability of Specht modules in general characteristic, and in particular the important role that endomorphisms play, thereby highlighting why this remains an open problem in characteristic 2. We will then present a new tool, influenced by the representation theory of algebraic groups, that can be used to show that a given Specht module has no non-trivial endomorphisms. As a proof of concept, we finish by using this tool to show that a certain large family of Specht modules are indecomposable. This presentation is based on joint work with my supervisor Dr. Haralampos Geranios, and is comprised of results from a paper that is currently in preparation. We aim to submit the paper before the end of the year.
