1: 21.8 Abelian Functions

§21.8 Abelian Functions

►An Abelian function is a $2g$-fold periodic, meromorphic function of $g$ complex variables. In consequence, Abelian functions are generalizations of elliptic functions (§23.2(iii)) to more than one complex variable. For every Abelian function, there is a positive integer $n$, such that the Abelian function can be expressed as a ratio of linear combinations of products with $n$ factors of Riemann theta functions with characteristics that share a common period lattice. …
