Heisenberg Group

In mathematics, the Heisenberg group, named after Werner Heisenberg, is the group of 3×3 upper triangular matrices of the form

\begin{pmatrix} 1 & a & c\\ 0 & 1 & b\\ 0 & 0 & 1\\ \end{pmatrix}

or its generalizations under the operation of matrix multiplication. Elements a, b and c, can be taken from some (arbitrary) commutative ring with identity, often taken to be the ring of real numbers or the ring of integers.

The real Heisenberg group arises in the description of one-dimensional quantum mechanical systems. More generally, one can consider groups associated to n-dimensional systems, and most generally, to any symplectic vector space.

Famous quotes containing the word group:

    “No other group in America has so had their identity socialized out of existence as have black women.... When black people are talked about the focus tends to be on black men; and when women are talked about the focus tends to be on white women.”
    —bell hooks (b. c. 1955)
