Strichartz estimates for orthonormal families of initial data and weighted oscillatory integral estimates

open access: yesForum of Mathematics, Sigma, 2021
We establish new Strichartz estimates for orthonormal families of initial data in the case of the wave, Klein–Gordon and fractional Schrödinger equations.

Fractional integral operators on central Morrey spaces

open access: yes, 2017
We consider the boudedness of fractional integral operators on localized (central) Morrey spaces and investigate the relation between the Adams inequality and the Spanne inequality. Mathematics subject classification (2010): 42B20, 42B25.

Weighted inequalities for the multilinear Hilbert and Calderón operators and applications

open access: yes, 2020
We characterize the weighted weak and strong type inequalities for the Hilbert and Calderón multilinear operators. As applications, we characterize a weighted multilinear Hilbert’s inequality and extend to the multilinear setting some results on singular

Global boundedness of a class of multilinear Fourier integral operators

open access: yesForum of Mathematics, Sigma, 2021
We establish the global regularity of multilinear Fourier integral operators that are associated to nonlinear wave equations on products of $L^p$ spaces by proving endpoint boundedness on suitable product spaces containing combinations of the local ...

LP → LQ - Estimates for the Fractional Acoustic Potentials and some Related Operators [PDF]

open access: yes, 2005
Mathematics Subject Classification: 47B38, 31B10, 42B20, 42B15.We obtain the Lp → Lq - estimates for the fractional acoustic potentials in R^n, which are known to be negative powers of the Helmholtz operator, and some related operators. Some applications

HARDY OPERATORS IN THE LOCAL ``COMPLEMENTARY" GENERALIZED VARIABLE EXPONENT WEIGHTED MORREY SPACES

open access: yes, 2020
In this paper we consider local “complementary” generalized weighted Morrey spaces M p(·),ω,φ {x0} (Ω) with variable exponent p(x) and a general function ω(r) defining the weighted Morrey-type norm.

Estimates for bilinear θ-type generalized fractional integral and its commutator on new non-homogeneous generalized Morrey spaces

open access: yesAnalysis and Geometry in Metric Spaces, 2023
Let (X,d,μ)\left({\mathcal{X}},d,\mu ) be a non-homogeneous metric measure space satisfying the geometrically doubling and upper doubling conditions. In this setting, we first introduce a generalized Morrey space Mpu(μ){M}_{p}^{u}\left(\mu ), where 1 ...

Estimates for evolutionary partial differential equations in classical function spaces

open access: yesForum of Mathematics, Sigma, 2023
We establish new local and global estimates for evolutionary partial differential equations in classical Banach and quasi-Banach spaces that appear most frequently in the theory of partial differential equations.
