Web190 Bounded Linear Operators on a Hilbert Space is an orthogonal projection of L2(R) onto the subspace of functions with support contained in A. A frequently encountered case is that of projections onto a one-dimensional subspace of a Hilbert space H.

WebIt is well known that a bounded normal operator has the property that the closure of its numerical range is exactly the con-vex hull of its spectrum [5, pp. 325-327, Theorem 8.13 and Theorem 8.14]. Call this property A. In this article let P denote a linear bounded operator in a Hilbert space H, V(T) be its numerical range, In mathematics, especially functional analysis, a normal operator on a complex Hilbert space H is a continuous linear operator N : H → H that commutes with its hermitian adjoint N*, that is: NN* = N*N. Normal operators are important because the spectral theorem holds for them. The class of normal operators is well … Ver mais Normal operators are characterized by the spectral theorem. A compact normal operator (in particular, a normal operator on a finite-dimensional linear space) is unitarily diagonalizable. Let Ver mais The definition of normal operators naturally generalizes to some class of unbounded operators. Explicitly, a closed operator N is said to be normal if $${\displaystyle N^{*}N=NN^{*}.}$$ Here, the existence of the adjoint N* requires that the … Ver mais • Continuous linear operator • Contraction (operator theory) – Bounded operators with sub-unit norm Ver mais If a normal operator T on a finite-dimensional real or complex Hilbert space (inner product space) H stabilizes a subspace V, then it … Ver mais The notion of normal operators generalizes to an involutive algebra: An element x of an involutive algebra is said to be normal if xx* = x*x.
