Multiplication operators in Köthe–Bochner spaces
Journal of Mathematical Analysis and Applications, 2011 Let X be a Banach space and E an order continuous Banach function space over a finite measure mu. We prove that an operator T in the Kothe-Bochner space E(X) is a multiplication operator (by a function in L(infinity)(mu)) if and only if the equality T(g < f, x*> x) = g < T(f), x*> x holds for every g is an element of L(infinity)(mu), f is an element of

Algebras of Variable Coefficient Quantized Differential Operators
, 2019 In the framework of (vector valued) quantized holomorphic functions defined on non-commutative spaces, ``quantized hermitian symmetric spaces'', we analyze what the algebras of quantized differential operators with variable coefficients should be.

Packaging of Macroscopic Material Payloads: Needs, Challenges, Concepts, and Future Directions
Advanced Engineering Materials, EarlyView.This review introduces a unified framework that decomposes any macroscopic packaging system into the payload, packaging material, and packaging strategy and combines them into a conceptual packaging equation: packaging strategy = payload + packaging material.

EURASIP Journal on Advances in Signal Processing, 2017 New theoretical lower bounds for the number of operators needed in fixed-point constant multiplication blocks are presented. The multipliers are constructed with the shift-and-add approach, where every arithmetic operation is pipelined, and with the ...

Cyclic vectors for multiplication operators.
Michigan Mathematical Journal, 1988 If \(E\) is a complex topological vector space and \(T\) a continuous linear transformation on \(E\), a vector \(x\in E\) is a cyclic vector for \(T\) if \(\{p(T)x: p\) a polynomial\(\}\) is dense in \(E\). If \(\mu\) is a compactly supported Borel measure on \(\mathbb C\), let \(X\) be the closed unit ball of \(L^{\infty}(\mu)\) and let \(X_ p\) be ...

Advanced Engineering Materials, EarlyView.It is shown that laser ablation pretreatment under oxygen‐free conditions enables copper–aluminium bonding at significantly lower deformation degrees and improved properties compared to mechanical brushing. Laser ablation further increases interface contact area and induces favourable residual stress states and microstructural compatibility ...

Advanced Engineering Materials, EarlyView.Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Boundedness and compactness of a new product-type operator from a general space to Bloch-type spaces
Journal of Inequalities and Applications, 2016 We characterize the boundedness and compactness of a product-type operator, which, among others, includes all the products of the single composition, multiplication, and differentiation operators, from a general space to Bloch-type spaces.
