Almost Block Diagonal Linear Systems
... The most general ABD matrix [32], shown in Figure 1..1, has the following characteristics: the nonzero elements lie in blocks which may be of different sizes; each diagonal entry lies in a block; any column of the matrix intersects no more than two blocks (which are successive), and the overlap betw ...

... In this thesis, we present a new class of algorithms that determine fast Fourier transforms for a given finite group G. These algorithms use eigenspace projections determined by a chain of subgroups of G, and rely on a path-algebraic approach to the representation theory of finite groups developed b ...
