Fujita exponents on quantum Euclidean spaces

Edward McDonald, Michael Ruzhansky, Serikbol Shaimardan +1

We study the well-posedness of a non-linear heat equation with power nonlinearity with positive initial data on quantum Euclidean spaces. We prove a noncommutative analogue of the…

On the -analogue of Duhamel's principle

Mohammed Elamine Sebih, Serikbol Shaimardan, Irfan Ali

In this paper, we revisit the classical Duhamel's principle and provide a self-contained proof of this fundamental tool for linear evolution equations and systems of coupled equati…

Hörmander type Fourier multiplier theorem and Nikolskii inequality on quantum tori, and applications

Michael Ruzhansky, Serikbol Shaimardan, Kanat Tulenov

In this paper, we study Hörmander type Fourier multiplier theorem and the Nikolskii inequality on quantum tori. On the way to obtain these results, we also prove some classical in…

boundedness of Fourier multipliers on quantum Euclidean spaces

M. Ruzhansky, S. Shaimardan, K. Tulenov

In this paper, we study Fourier multipliers on quantum Euclidean spaces and obtain results on their boundedness. On the way to get these results, we prove Paley, Hausdor…

Sobolev inequality and its applications to nonlinear PDE on noncommutative Euclidean spaces

Michael Ruzhansky, Serikbol Shaimardan, Kanat Tulenov

In this work, we study the Sobolev inequality on noncommutative Euclidean spaces. As a simple consequence, we obtain the Gagliardo-Nirenberg type inequality and as its application…

Fourier multipliers and their applications to PDE on the quantum Euclidean space

M. Ruzhansky, S. Shaimardan, K. Tulenov

In this work, we present some applications of the - boundedness of Fourier multipliers to PDEs on the noncommutative (or quantum) Euclidean space. More precisely, we esta…
