Combinatorial Properties of Matrices,Let . be a subset of a number field, and let ..(.) denote the set of all . × . matrices with entries in ., and let ..(.) = ..(.). Note that .. = ..({0,1}). We write .. = ..({. ≥ 0| . is real}) and .*. = ..({. > 0| . is real}). When the set . is not specified, we write .., and .. for ..(.) and ..(.), respectively.
