Introduction and motivation: theta functions in one variable

  • David Mumford
Part of the Progress in Mathematics book series (PM, volume 28)


The central character in our story is the analytic function ϑ(z, τ) in 2 variables defined by
where z є ℂ and τ є H, the upper half plane Im τ > 0. It is immediate that the series converges absolutely and uniformly on compact sets; in fact, if
hence, if no is chosen so that
then the inequality
shows that the series converges and that too very rapidly.
