Weak transversality and partially invariant solutions [PDF]

open access: yesJournal of Mathematical Physics, 2003
New exact solutions are obtained for several nonlinear physical equations, namely the Navier–Stokes and Euler systems, an isentropic compressible fluid system and a vector nonlinear Schrödinger equation. The solution method makes use of the symmetry group of the system in situations when the standard Lie method of symmetry reduction is not applicable.

Local Hölder Regularity of Weak Solutions for Singular Parabolic Systems of p-Laplacian Type

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2021
In this paper, the Hölder regularity of weak solutions for singular parabolic systems of p-Laplacian type is investigated. By the Poincare inequality, we show that its weak solutions within Hölder space.

Bounded weak solutions to nonlinear elliptic equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2009
In this work, we are concerned with a class of elliptic problems with both absorption terms and critical growth in the gradient. We suppose that the data belong to $L^{m}(\Omega)$ with $m>n/2$ and we prove the existence of bounded weak solutions via $L^{\

Weak solutions with unbounded variation [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
To solve a quasilinear system of hyperbolic partial differential equations with given initial data, the usual procedure is to approximate the initial data, solve the resulting problems, and show that the variation of the approximating solutions is uniformly bounded. A limiting process then can be used.

Interior regularity of weak solutions to the perturbed Navier-Stokes equations [PDF]

open access: yes, 2012
summary:In this paper we establish interior regularity for weak solutions and partial regularity for suitable weak solutions of the perturbed Navier-Stokes system, which can be regarded as generalizations of the results in L. Caffarelli, R.

On the Regularity of Weak Solutions to Time-Periodic Navier–Stokes Equations in Exterior Domains

open access: yes, 2022
Consider the time-periodic viscous incompressible fluid flow past a body with non-zero velocity at infinity. This article gives sufficient conditions such that weak solutions to this problem are smooth.

Uniqueness in the Freedericksz transition with weak anchoring [PDF]

open access: yes, 2009
In this paper we consider a boundary value problem for a quasilinear pendulum equation with nonlinear boundary conditions that arises in a classical liquid crystals setup, the Freedericksz transition, which is the simplest opto-electronic switch, the ...

Global Existence and Uniqueness of Helically Symmetric Weak Solutions to the Ginzburg–Landau Model in Superconductivity

open access: yesMathematics
This manuscript proves the global existence and uniqueness of helically symmetric weak solutions to the 3D time-dependent Ginzburg–Landau model of superconductivity in R3 with L2 initial data and supports the choice of the Lorentz gauge.
