Modularity of Galois Representations

Explore the deep connections between Galois representations and modular forms in this comprehensive mathematical lecture that delves into one of the most significant areas of modern number theory. Learn about the fundamental concepts of Galois representations, their construction, and the profound modularity theorems that establish when these representations arise from modular forms. Discover the historical development from the Taniyama-Shimura conjecture through Wiles' proof of Fermat's Last Theorem to contemporary advances in the Langlands program. Examine specific techniques for proving modularity results, including the use of deformation theory, Hecke algebras, and automorphic forms. Understand how modularity theorems have revolutionized our understanding of elliptic curves, L-functions, and arithmetic geometry. Gain insight into current research directions and open problems in this rapidly evolving field that sits at the intersection of algebraic number theory, representation theory, and arithmetic geometry.
