www.math.uh.edua. For 1 k p, the dimension of the eigenspace for k is less than or equal to the multiplicity of the eigenvalue k. b. The matrix A is diagonalizable if and only if the sum of the dimensions of the distinct eigenspaces equals n, and this happens if and only if the dimension of the eigenspace for each k equals the multiplicity of k. c.

The algebraic multiplicity of is the multiplicity of the zero at t= in the characteristic polynomial ˜ A(t). The geometric multiplicity of an eigenvalue is equal to dimension of the eigenspace E or nullity(A tI). Theorem 7.1.6.

www.math.umd.edub) The dimension of the eigenspace for each eigenvalue λ equals the multiplicity of λ as a root of the characteristic polynomial of A. c) The eigenspaces are mutually orthogonal, in the sense that eigenvectors corresponding to different eigenvalues are orthogonal.
Object Recognition from Local Scale-Invariant Features
