In mathematics , the theta representation is a particular representation of the Heisenberg group of quantum mechanics . It gains its name from the fact that the Jacobi theta function is invariant under the action of a discrete subgroup of the Heisenberg group. The representation was popularized by David Mumford . Construction The theta representation is a representation of the continuous Heisenberg group math H 3 mathbb R math over the field of the real numbers. In this representation, the group elements act on a particular Hilbert space . The construction below proceeds first by defining operator mathematics operator s that correspond to the Heisenberg group generators. Next, the Hilbert space on which these act is defined, followed by a demonstration of the isomorphism to the usual representations. Group generators Let f z be a holomorphic function , let a and b be real number s, and let math tau math be fixed, but arbitrary complex number in the upper half plane that is, so that the imaginary part of math tau math is positive. Define the operators S sub a sub and T sub b sub such that they act on holomorphic functions as math S a f z f z a math and math T b f z exp i pi b 2 tau 2 pi ibz f z b tau . math It can be seen that each operator generates a one parameter subgroup math S a 1 ... irreducible .
