Invariance for multiples of the twisted canonical bundle [PDF]

, 2006
In this paper, we show an extension type theorem for twisted pluricanonical sections on a family of smooth projective manifolds (the twisting line bundle being pseudo-effective and having a prescribed multiplier ideal on the central fiber).Comment: A ...

Solution Formula of Korteweg Type by Using Partial Fourier Transform Methods in Half-Space without Surface Tension

JTAM (Jurnal Teori dan Aplikasi Matematika), 2023
Sharp-interface models and diffuse-interface models are the two basic types of models that describe liquid-vapour flow for compressible fluids. Their depictions of the line dividing liquid from vapour are different.

Bilinear Fourier Multipliers of Bounded Variation

International Mathematics Research Notices, 2022
Abstract In this paper, we obtain weighted estimates for bilinear Fourier multipliers of bounded variation that provide new restricted weak-type bounds. We also study their boundedness on the setting of the weighted Lorentz spaces. The results are obtained using Rubio de Francia extrapolation as the main tool.

Numerical Analysis of Fourier Finite Volume Element Method for Dirichlet Boundary Optimal Control Problems Governed by Elliptic PDEs on Complex Connected Domains

Mathematics, 2022
In this research, we investigate an optimal control problem governed by elliptic PDEs with Dirichlet boundary conditions on complex connected domains, which can be utilized to model the cooling process of concrete dam pouring.

A brief description of operators associated to the quantum harmonic oscillator on Schatten-von Neumann classes

Revista Integración, 2018
In this note we study pseudo-multipliers associated to the harmonic oscillator (also called Hermite multipliers) belonging to Schatten classes on L2(Rn). We also investigate the spectral trace of these operators.

Multilinear Fourier multipliers on variable Lebesgue spaces [PDF]

, 2014
In this paper, we study properties of the bilinear multiplier space. We give a necessary condition for a continuous integrable function to be a bilinear multiplier on variable exponent Lebesgue spaces. And we prove the localization theorem of multipliers

Spherical-Radial Multipliers on the Heisenberg Group

International Journal of Analysis and Applications, 2020
Let Hn be the (2n+1)-dimensional Heisenberg group. We consider a radial Fourier multiplier which is a spherical function on Hn and show that it is a Herz-Schur multiplier.

Cardinal Interpolation with Gaussian Kernels

, 2010
In this paper, interpolation by scaled multi-integer translates of Gaussian kernels is studied. The main result establishes $L_p$ Sobolev error estimates and shows that the error is controlled by the $L_p$ multiplier norm of a Fourier multiplier closely ...

Wave packet analysis of Schrodinger equations in analytic function spaces [PDF]

, 2015
We consider a class of linear Schroedinger equations in R^d, with analytic symbols. We prove a global-in-time integral representation for the corresponding propagator as a generalized Gabor multiplier with a window analytic and decaying exponentially at ...
