Best Approximations in Hardy Spaces on Infinite-Dimensional Unitary Matrix Groups

open access: yesAbstract and Applied Analysis, 2014
We investigate the problem of best approximations in the Hardy space of complex functions, defined on the infinite-dimensional unitary matrix group. Applying an abstract Besov-type interpolation scale and the Bernstein-Jackson inequalities, a behavior of

The Asymptotic Properties of Turbulent Solutions to the Navier-Stokes Equations

open access: yesActa Polytechnica, 2012
In this paper we study the large time behavior of solutions to the Navier-Stokes equations. We present a brief survey of results concerning energy decay, and discuss a related phenomenon of the large time energy concentration in the frequency space ...

Well-posedness of degenerate integro-differential equations in function spaces

open access: yesElectronic Journal of Differential Equations, 2018
We use operator-valued Fourier multipliers to obtain characterizations for well-posedness of a large class of degenerate integro-differential equations of second order in time in Banach spaces.

Global mild solutions to modified Navier-Stokes equations with small initial data in critical Besov-Q spaces

open access: yesElectronic Journal of Differential Equations, 2014
This article is devoted to establishing the global existence and uniqueness of a mild solution of the modified Navier-Stokes equations with a small initial data in the critical Besov-Q space.

Local and global existence for the Lagrangian Averaged Navier-Stokes equations in Besov spaces

open access: yesElectronic Journal of Differential Equations, 2012
Through the use of a non-standard Leibntiz rule estimate, we prove the existence of unique short time solutions to the incompressible, iso-tropic Lagrangian Averaged Navier-Stokes equation with initial data in the Besov space $B^{r}_{p,q}(mathbb{R}^n)$
