Linear Transformations,g general properties of the endomorphism algebra .(.) on ., where . is the field of real or complex numbers. The endomorphism algebra .(.) exists independently of any further structure which may be assumed on V, such as a nondegenerate inner product induced by a quadratic form of arbitrary signature
