Jackson-Slater Identity


The Jackson-Slater identity is the q-series identity of Rogers-Ramanujan-type given by

sum_(k=0)^(infty)(q^(2k^2))/((q)_(2k))=((q,q^7,q^8;q^8)_infty(q^6,q^(10);q^(16))_infty)/((q)_infty)
(1)
=(f(q^3,q^5))/(f(-q^2))
(2)
=1+q^2+q^3+2q^4+2q^5+3q^6+3q^6+5q^7+...
(3)

(OEIS A069910; Leininger and Milne 1999), where (a^i,b^j,...,a^p;q)_infty is extended q-series notation and f(a,b) is a Ramanujan theta function.

The identity in question was actually first published by Jackson (1928) in slightly disguised form as the fifth equation on page 170 in his paper, though this early appearance of this identity is not well-known. It became widely known as equation 39 (and 83) in the collection of identities due to Slater (1952).
