Hilbert spaces are complete, and this allows one to develop the notion of an infinite-dimensional basis. The prototypic Hilbert space is L 2(I) Some of the points introduced in Lesson 4, including orthogonal projections, will be formalized....
It can be shown L^2 is a complete space under the induced norm \|f\|_{L^2} . Thus, H:=L^2(X, d\mu) is a Hilbert space. Fix g\in H , define T: H\rightarrow \mathbb{R} as Tf:=\langle f, g\rangle . It can be shown T is a linear functional and \|T\|_{op}=\...

The meaning of HILBERT SPACE is a vector space for which a scalar product is defined and in which every Cauchy sequence composed of elements in the space converges to a limit in the space.
As a complete normed space, Hilbert spaces are by definition also Banach spaces. As such they are topological vector spaces, in which topological notions like the openness and closedness of subsets are well-defined. Of special importance is the notion of a closed linear subspace of a Hilbert ...
This infinite-dimensional Ornstein–Uhlenbeck-type of dynamics, taking values in a separable Hilbert space, is assumed to be modulated by an operator-valued extension of the Barndorff-Nielsen and Shephard [3] stochastic volatility model. Moreover, we propose to include a leverage effect in the ...

A vector space with a norm is a normed linear space. A normed linear space, which is complete with respect to the norm is a Banach space. That is, a Banach space is a normed linear space in which Cauchy sequences converge. 展开 ...
This chapter discusses weak convergence in separable Hilbert spaces. If a linear space has a scalar product and a norm and is complete in the metric, it is called a Hilbert space. Any separable Hilbert space is isometric to l2; hence, the l2-space is a representative of a rather general ...
