Eigenspaces - CliffsNotes
www.cliffsnotes.com › study-guides › algebraforms a vector space called the eigenspace of A correspondign to the eigenvalue λ. Since it depends on both A and the selection of one of its eigenvalues, the notation will be used to denote this space. Since the equation A x = λ x is equivalent to ( A − λ I) x = 0, the eigenspace E λ ( A) can also be characterized as the nullspace of A − λ I:
