Semi-simple operator
From Wikipedia, the free encyclopedia
(Redirected from Semisimple operator)
In mathematics, a linear operator T on a finite dimensional vector space, is semi-simple if every T-invariant subspace has a complementary T-invariant subspace.
An important result regarding semi-simple operators is that, a linear operator on a finite dimensional vector space over an algebraically closed field is semi-simple if and only if it is diagonalizable.
