The Ramanujan theta function, denoted as \\(\\theta(q)\\), is a special function that arises in partition theory and modular forms, and has connections to various areas of mathematics, including combinatorial identities and number theory. It is specifically defined for a complex number \\(q\\) where \\( |q| \< 1\\).
