In mathematics, the Neville theta functions, named after Eric Harold Neville, are defined as follows: The Mathematical Functions Site The Mathematical Functions Site
where: K(m) is the complete elliptic integral of the first kind, , and is the elliptic nome.
Note that the functions θp(z,m) are sometimes defined in terms of the nome q(m) and written θp(z,q) (e.g. NIST). The functions may also be written in terms of the τ parameter θp(z|τ) where .
Relationship to other functions
The Neville theta functions may be expressed in terms of the Jacobi theta functions
where .
The Neville theta functions are related to the Jacobi elliptic functions. If pq(u,m) is a Jacobi elliptic function (p and q are one of s,c,n,d), then
