Multiple Operator Integrals

2019
Theory of multiple operator integrals arose as an extension of the double operator integration theory to the settings that could not be encompassed by the latter constructions. In particular, multilinear transformations naturally arise in finding summable approximations to operator functions in the case of nontrace class perturbations, as we will see ...

Multiple almost summing operators

2021
In this paper, we explore the concept of multilinear operators that are multiple almost summing and present a new concept of type and cotype of multilinear operators and investigate the conditions for this new concept to recover the original concept of type and type for multilinear operators.

Duality and multiplication operators

Integral Equations and Operator Theory, 1991
Let \(\mathbb{D}\) denote the open unit disk and let \(dA\) denote the normalized Lebesgue measure on \(\mathbb{D}\). The Bergman space is defined by \({\mathcal L}_ a^ p=\{f\); \(f:\mathbb{D}\to\mathbb{C}\), \(f\) analytic and \(\int_ D| f(z)|^ 2 dA(z)

Multiplicative Operator Functionals

1997
Multiplicative operator functionals ( MOF ) are a generalization of real multiplicative functionals from the probabilistic point of view and a stochastic analogue of semigroups of operators from the functional analysis point of view.

Unstable multiplicative cohomology operations

The Quarterly Journal of Mathematics, 2000
For a homology theory \(E_*(-)\) an \(E\)-detecting category for a space \(X\) is a subcategory \(C\) of the homotopy category, closed under finite products such that there is an isomorphism \(J:\text{colim} E_*(Z)\to E_*X\) where \(C_X\) is the category with \(C_X\) objects the homotopy classes of maps \(Z\to X\) \((Z\in C)\) and obvious morphisms ...

Multiple-Operation Machining

1989
Abstract This article provides information on the operating principle, tool material and design changes, and safety and protection of various multifunction machines as well as the cutting fluids used. These include single-spindle automatic lathes, manual turret lathes, single-spindle automatic bar and chucking machines, Swiss-type ...

Classes of Multiplication Operators and Their Limit Operators

Zeitschrift für Analysis und ihre Anwendungen, 2004
Limit operators have proven to be a device for the study of several properties of an operator including Fredholmness and invertibility at infinity, but also the applicability of approximation methods. For band-dominated operators, the question of existence and structure of their limit operators essentially reduces to the study of multiplication ...

Bicommutants of multiplication operators

Positivity, 2010
Let \(X\) be a Banach space and let \(L(X)\) be the space of all linear continuous operators on \(X\). For \(T \in L(X)\), let \(\mathcal A_T\) denote the closure of the algebra generated by \(T\) and the identity operator \(I\) in the weak operator topology.
