This facsimile of the 1950 edition by Clarendon Press includes all the original material, covering matrices, algebras, groups, the Frobenius algebra, the symmetric group, immanants and S-functions, the S-functions of special series, the calculation of the characters of the symmetric group, group characters and the construction of groups, continuous matrix groups and invariant matrices, and groups of unitary matrices
Killip and Nenciu  describe an ensemble of n x n random unitary matrices
whose eigenvalues are distributed according to the Gibbs distribution for n particles of the Coulomb gas on the unit circle.
The CMV and unitary matrices
in general are linked to orthogonal polynomials on the unit circle for which a rich variety of literature is available; early contributions and references can be found in [1-3].
which, for unitary matrices
, links closely to CMV matrices .
where U and V are unitary matrices
, and [SIGMA] is a diagonal matrix where the diagonal entries are real and nonnegative and satisfy [[sigma].
At each iteration, there exist unitary matrices
A singular value decomposition of a non-zero complex N x N matrix B is an expression of B as a product B = V[SIGMA]W*, where V and W are unitary matrices
A quantum computation applies a unitary matrix to a vector , and quantum (logic) circuits are a notational shorthand for factorizations of such unitary matrices
into more basic ones, corresponding to gates.
