FAQ About Srinivasa Ramanujan

Mock theta functions are a class of q-series introduced by Ramanujan in his last letter to G.H. Hardy in 1920, shortly before his death. They are important because they are related to the theory of modular forms and have applications in both pure mathematics and theoretical physics. The study of mock theta functions has continued to be an area of rich mathematical research, providing deep insights into the modularity of various mathematical objects.
