Theta functions of binary quadratic forms with congruence conditions as ray class theta functions
. We prove that theta functions of binary quadratic forms with congruence conditions coincide with theta functions attached to ray classes of quadratic (cid:12)elds. By Hecke’s Theorem, we can construct Hecke eigenforms by forming linear combinations of them.
