Title: Subconvexity bound problem for L-functions
Abstract: Study of L-functions is one of the central themes of modern
number theory. The problem of bounding growth rate of L-functions is
classical and goes back to Weyl (1916), who proved the first non-trivial
result for the Riemann zeta function. This is known as the subconvexity
bound problem and has various applications, apart from being of
independent interest. We will talk about the history of the problem, give
some applications, and present some classical analytic tools like the
circle method used to study the problem.
