Results from the theory of linear models establish a particular idempotency condition as being necessary and sufficient for a quadratic form in a nonsingular normal vector to follow a chi-square ...

Let A, B be artinian rings and let AM B be an (A - B)-bimodule which is a finitely generated left A-module and a finitely generated right B-module. A right AM B-prinjective module is a finitely ...

An equation of the form \(y = mx + c\) where \(m\) and \(c\) are numbers, gives a straight line when values of \(x\) and corresponding values of \(y\) are plotted on a grid. A straight line is a ...
