Multiplicative Lower-Upper Triangular Decompositions of Operatorst, under certain conditions, a matrix can be represented as a product of a lower with an upper triangular matrix. Also, the possibility of factoring certain integral operators as the product of integral operators with lower and upper triangular kernel functions is treated as a special case of the general theory which we now develop.作者: GLARE 時間: 2025-3-22 17:06

https://doi.org/10.1007/b101825This chapter contains the Stone-Weierstrass theorem and the Gelfand-Naimark representation theorem for commutative Banach algebras with an involution. The latter theorem is used to derive the spectral theorem for a normal operator. The Gelfand-Naimark characterization of a .*-algebra as a closed *-subalgebra of operators is also presented.作者: Spongy-Bone 時間: 2025-3-24 15:37

Block Toeplitz OperatorsThe first three sections of this chapter have an introductory character. Section 2 contains a short introduction to Laurent operators. In Section 3 the first properties of block Toeplitz operators are derived. Sections 4 and 5 develop the Fredholm theory of block Toeplitz operators defined by continuous functions.作者: 從屬 時間: 2025-3-25 00:41 作者: vitreous-humor 時間: 2025-3-25 04:18 作者: asthma 時間: 2025-3-25 07:41 作者: Cultivate 時間: 2025-3-25 13:15

Dilation Theoryrs. The minimal isometric and minimal unitary dilations of a given contraction are to a large extent unique, which implies that those operators are useful instruments for the analysis of contractions. In this chapter we also prove the commutant lifting theorem and present some of its applications to interpolation problems.作者: 聯(lián)邦 時間: 2025-3-25 22:37 作者: 不利 時間: 2025-3-26 03:01 作者: 過于光澤 時間: 2025-3-26 06:24 作者: 混合物 時間: 2025-3-26 08:37 作者: 單調(diào)性 時間: 2025-3-26 16:40

Banach Algebras Generated by Toeplitz Operatorstudied. These algebras are not commutative, but they contain the compact operators as a proper closed ideal and in the scalar case the corresponding quotient algebras turn out to be commutative. The Gelfand spectra and transforms of these quotient algebras are described and analyzed.
