# Linear functions on the classical matrix groups

@article{Meckes2005LinearFO, title={Linear functions on the classical matrix groups}, author={Elizabeth S. Meckes}, journal={Transactions of the American Mathematical Society}, year={2005}, volume={360}, pages={5355-5366} }

Let M be a random matrix in the orthogonal group On, distributed according to Haar measure, and let A be a fixed n x n matrix over R such that Tr(AA t ) = n. Then the total variation distance of the random variable Tr(AM) to a standard normal random variable is bounded by 2√3 n-1 and this rate is sharp up to the constant. Analogous results are obtained for M a random unitary matrix and A a fixed n x n matrix over C. The proofs are applications of a new abstract normal approximation theorem… Expand
