New Results on Gevrey Well Posedness for the Schrödinger–Korteweg–De Vries System

open access: yesMathematical and Computational Applications
In this work, we prove that the initial value problem for the Schrödinger–Korteweg–de Vries (SKdV) system is locally well posed in Gevrey spaces for s>−34 and k≥0. This advancement extends recent findings regarding the well posedness of this model within

On the stability threshold for the 3D Couette flow in Sobolev regularity [PDF]

open access: yes, 2015
We study Sobolev regularity disturbances to the periodic, plane Couette flow in the 3D incompressible Navier-Stokes equations at high Reynolds number $\textbf{Re}$.

Application of Multiscale Entropy in Assessing Plantar Skin Blood Flow Dynamics in Diabetics with Peripheral Neuropathy

open access: yesEntropy, 2018
Diabetic foot ulcer (DFU) is a common complication of diabetes mellitus, while tissue ischemia caused by impaired vasodilatory response to plantar pressure is thought to be a major factor of the development of DFUs, which has been assessed using various ...

Mild Solution for the Time-Fractional Navier–Stokes Equation Incorporating MHD Effects

open access: yesFractal and Fractional, 2022
The Navier–Stokes (NS) equations involving MHD effects with time-fractional derivatives are discussed in this paper. This paper investigates the local and global existence and uniqueness of the mild solution to the NS equations for the time fractional ...

Stochastic PDEs, Regularity Structures, and Interacting Particle Systems [PDF]

open access: yes, 2015
These lecture notes grew out of a series of lectures given by the second named author in short courses in Toulouse, Matsumoto, and Darmstadt. The main aim is to explain some aspects of the theory of "Regularity structures" developed recently by Hairer in

Depth and regularity of powers of sums of ideals [PDF]

open access: yes, 2015
Given arbitrary homogeneous ideals I and J in polynomial rings A and B over a field k, we investigate the depth and the Castelnuovo–Mumford regularity of powers of the sum $$I+J$$I+J in $$A \otimes _k B$$A⊗kB in terms of those of I and J. Our results can

AI based algorithms for the detection of (ir)regularity in musical structure

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2020
Regularity in musical structure is experienced as a strongly structured texture with repeated and periodic patterns, with the musical ideas presented in an appreciable shape to the human mind. We recently showed that manipulation of musical content (i.e.,
