**Venue**: Lecture Hall I, Department of Mathematics

**Abstract**: The sin function is an example of a periodic complex function. In this talk, we will explore the space of doubly periodic functions of a complex variable, i.e., the space of all f:ℂ→ ℂ such that f(z) = f(z+ω

_{1}) = f(z+ω

_{2}) ∀z∈ℂ, for two “real”ly independent periods ω

_{1}, ω

_{2}∈ℂ. Finally, by letting one of these periods go to infinity, we get a method to extract values of the Riemann ζ function.

**Prerequisites**: Complex Analysis

**Area**: Functions of One Complex Variable
