Bibliography. Bounded operator. In functional analysis and operator theory, a bounded linear operator is a linear transformation between topological vector spaces (TVSs) and that maps bounded subsets of to bounded subsets of If and are normed vector spaces (a special type of TVS), then is bounded if and only if there exists some such that for all.
Hace 4 días · A bounded operator T:V->W between two Banach spaces satisfies the inequality ||Tv||<=C||v||, (1) where C is a constant independent of the choice of v in V. The inequality is called a bound. For example, consider f=(1+x^2)^(-1/2), which has L2-norm pi^(1/2).
Definition 24. Let V and W be two normed spaces. The set of bounded linear operators from V to W is denoted B(V; W). We can check that B(V; W) is a vector space – the sum of two linear operators is a linear operator, and so on. Furthermore, we can put a norm on this space:

Bounded Linear Operators on a Hilbert Space. In this chapter we describe some important classes of bounded linear operators on Hilbert spaces, including projections, unitary operators, and self-adjoint operators. We also prove the Riesz representation theorem, which characterizes the bounded linear functionals on a Hilbert space, and discuss ...

F) are normed vector spaces, a bounded operator from E to F is a continuous linear mapping T : E →F, i.e, such that ∃C > 0, ∀u ∈E, ∥Tu∥ F ≤C ∥u∥ E. Notation. We denote by L(E, F) the set of bounded operators from E to F. When E = F, we write L(E) = L(E, E). L(E, F) is a vector space on which we introduce the norm, ∥T∥ L(E ...
