Spaces of Pointwise Multipliers on Morrey Spaces and Weak Morrey Spaces
Mathematics, 2021 The spaces of pointwise multipliers on Morrey spaces are described in terms of Morrey spaces, their preduals, and vector-valued Morrey spaces introduced by Ho. This paper covers weak Morrey spaces as well.

Pointwise Multipliers on Weak Morrey Spaces
Analysis and Geometry in Metric Spaces, 2020 We consider generalized weak Morrey spaces with variable growth condition on spaces of homogeneous type and characterize the pointwise multipliers from a generalized weak Morrey space to another one.

Traces of multipliers in pairs of weighted Sobolev spaces
Journal of Function Spaces and Applications, 2005 We prove that the pointwise multipliers acting in a pair of fractional Sobolev spaces form the space of boundary traces of multipliers in a pair of weighted Sobolev space of functions in a domain.

Smooth pointwise multipliers of modulation spaces
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012 Let 1 < p, q < ∞ and s, r ∈ ℝ. It is proved that any function in the amalgam space W(Hrp(ℝd), ℓ∞), where p' is the conjugate exponent to p and Hrp′ (ℝd) is the Bessel potential space, defines a bounded pointwise multiplication operator in the modulation ...

Modeling Variational Inpainting Methods With Splines
Frontiers in Applied Mathematics and Statistics, 2019 Mathematical methods of image inpainting often involve the discretization of a given continuous model. Typically, this is done by a pointwise discretization.

On optimality and duality in nonsmooth vector fractional continuous-time programming: Strengthened conditions for mixed-affine models [PDF]
Theoretical and Applied MechanicsWe investigate a nonsmooth vector fractional continuous-time programming problem with inequality-type phase constraints, motivated by applied-mechanics contexts in which performance is quantified by ratio-type, time-accumulated indices under pointwise-in-

Estimates of Reachable Set and Sufficient Optimality Condition for Discrete Control Problems
Известия Иркутского государственного университета: Серия "Математика", 2017 The paper follows the “canonical optimality theory” (in the terminology due to A. A. Milyutin) for discrete-time optimal control problems. In respect of optimality conditions, the feature of this approach is to employ sets of strongly monotone functions ...

Pointwise Multipliers on Spaces of Homogeneous Type in the Sense of Coifman and Weiss
Abstract and Applied Analysis, 2014 By applying the remarkable orthonormal basis constructed recently by Ausher and Hytönen on spaces of homogeneous type in the sense of Coifman and Weiss, pointwise multipliers of inhomogeneous Besov and Triebel-Lizorkin spaces are obtained.
