In mathematics, a doubly periodic function is a function defined on the complex plane and having two "periods", which are complex numbers u {\displaystyle u} and v {\displaystyle v} that are linearly independent as vectors over the field of real numbers. That u {\displaystyle u} and v {\displaystyle v} are periods of a function f {\displaystyle f} means that
