Removing rotated discretely self-similar singularity for the Euler equations

D Chae - Journal of Differential Equations, 2023 - Elsevier
In this paper we exclude the scenario of rotated discretely self-similar singularities of the 3D
incompressible Euler equations in the case when the singularity point is isolated and the …

On Liouville type theorems for the self-similar solutions to the generalized Euler equations

D Chae - Advances in Mathematics, 2023 - Elsevier
We study the backward discretely self-similar solutions to the generalized Euler equations,
where usual Biot-Savart kernel representing the velocity in terms of the vorticity is replaced …

Local Energy Solutions to the Navier--Stokes Equations in Wiener Amalgam Spaces

Z Bradshaw, TP Tsai - SIAM Journal on Mathematical Analysis, 2021 - SIAM
We establish existence of solutions in a scale of classes weaker than the finite energy Leray
class and stronger than the infinite energy Lemarié-Rieusset class. The new classes are …

Self-similarity in turbulence and its applications

K Ohkitani - … Transactions of the Royal Society A, 2022 - royalsocietypublishing.org
First, we discuss the non-Gaussian type of self-similar solutions to the Navier–Stokes
equations. We revisit a class of self-similar solutions which was studied in Canonne et …

Local well-posedness of perturbed Navier-Stokes system around Landau solutions

Z Jingjing, Z Ting - Electronic Research Archive, 2021 - aimsciences.org
For the incompressible Navier-Stokes system, when initial data are uniformly locally square

Time-Global Regularity of the Navier-Stokes System with Hyper-Dissipation--Turbulent Scenario

Z Grujic, L Xu - arXiv preprint arXiv:2012.05692, 2020 - arxiv.org
The question of whether the hyper-dissipative (HD) Navier-Stokes (NS) system can exhibit
spontaneous formation of singularities in the super-critical regime--the hyper-dissipation …

[HTML][HTML] Incompressible flows: Relative scale invariance and isobaric polynomial fields

J Polihronov - AIP Advances, 2022 - pubs.aip.org
This article examines the Bouton–Lie group invariants of the Navier–Stokes equation (NSE)
for incompressible fluids. The theory is applied to the general scaling transformation …
