    Talk Title
    Toward Faster Algebraic Computation: An Isomorphism Perspective

    Abstract

    "Over the past few decades, linear-algebraic techniques played a central role in the design of faster algorithms, with notable successes in many graph algorithms such as maximum flow and shortest paths. However, for many problems that are not yet known to admit polynomial-time algorithms—such as integer factoring and various isomorphism problems—linear methods alone are often insufficient. In these settings, more general nonlinear algebraic structures, including groups, rings, and modules, naturally arise. Achieving further algorithmic progress requires a deeper understanding of these algebraic objects.

    In this talk, I will discuss how algebraic representations have become essential to recent advances in isomorphism problems. I will highlight connections among several central isomorphism problems and survey the techniques that have led to more efficient algorithms. I will conclude by discussing open challenges and outlining promising directions for future research."
