Hilbert space infinite dimensional

WebIn the finite-dimensional case, part of the first approach works in much greater generality; any square matrix, not necessarily Hermitian, has an eigenvector. This is simply not true for general operators on Hilbert spaces. In infinite dimensions, it is also not immediate how to generalize the concept of the characteristic polynomial. WebNov 14, 2011 · For an infinite-dimensional Hilbert space with complete orthonormal basis , let A complete orthonormal basis for is , which is countable, since the Cartesian product of countable sets is countable. By induction, every space has a countable orthonormal basis.
