Book Review: Polynomial and Matrix Computations Volume 1: Fundamental Algorithms by D. Bini and V. Pan

We discuss a generalization of the Cohn---Umans method, a potent technique developed for studying the bilinear complexity of matrix multiplication by embedding matrices into an appropriate group algebra. We investigate how the Cohn---Umans method may be ...

Classical Schur's matrix is a different evaluation, provided by Schur, of the quadratic Gaussian sum from Gauss. The advanced information was studied by L. Carlitz who determined its eigenvalues, and by P. Morton who determined its eigenvectors. In this ...
