In the special case where D is defined on a function space, the eigenvectors are referred to as eigenfunctions. come the night nick blake
7.1: Eigenvalues and Eigenvectors of a Matrix
WebDe nition 1. For a given linear operator T: V ! V, a nonzero vector x and a constant scalar are called an eigenvector and its eigenvalue, respec-tively, when T(x) = x. For a given eigenvalue , the set of all x such that T(x) = x is called the -eigenspace. The set of all eigenvalues for a transformation is called its spectrum. The following table presents some example transformations in the plane along with their 2×2 matrices, eigenvalues, and eigenvectors. The characteristic equation for a rotation is a quadratic equation with discriminant , which is a negative number whenever θ is not an integer multiple of 180°. Therefore, except for these special cases, the two eigenvalues are complex n… WebIn linear algebra and functional analysis, the min-max theorem, or variational theorem, or Courant–Fischer–Weyl min-max principle, is a result that gives a variational characterization of eigenvalues of compact Hermitian operators on Hilbert spaces.It can be viewed as the starting point of many results of similar nature.
