ABSTRACT. The book is an introduction to the theory of Theta Functions and Theta Constants
with rational characteristics showing their close connections to Riemann Surfaces and the Modular
Group. Applications to uniformization theorems, partition identities and combinatorial number
theory are developed. Projective embeddings of modular curves and Ramanujan partition congru-
ences are explored. Theta identities and their combinatorial contents are studied. Many examples
are provided, and directions for future studies are indicated.
