Optimal Interior Partial Regularity for Nonlinear Elliptic Systems for the Case 1<m<2 under Natural Growth Condition

open access: yesJournal of Inequalities and Applications, 2010
We consider the interior regularity for weak solutions of second-order nonlinear elliptic systems with subquadratic growth under natural growth condition.

A regularity criterion for the three-dimensional micropolar fluid system in homogeneous Besov spaces

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
By establishing a new trilinear estimate, we show a regularity criterion for the three dimensional micropolar fluid system via the velocity in homogeneous Besov spaces. This improves [B. Q. Dong, Z. L.

Online Regularized Nonlinear Acceleration

open access: yes, 2018
Regularized nonlinear acceleration (RNA) estimates the minimum of a function by post-processing iterates from an algorithm such as the gradient method. It can be seen as a regularized version of Anderson acceleration, a classical acceleration scheme from numerical analysis. The new scheme provably improves the rate of convergence of fixed step gradient

A note on regularity and failure of regularity for systems of conservation laws via Lagrangian formulation

open access: yes, 2015
The paper recalls two of the regularity results for Burgers' equation, and discusses what happens in the case of genuinely nonlinear, strictly hyperbolic systems of conservation laws.

Positive solutions for (p, q)-equations with convection and a sign-changing reaction

open access: yesAdvances in Nonlinear Analysis, 2021
We consider a nonlinear Dirichlet problem driven by the (p, q)-Laplacian and with a reaction which is dependent on the gradient. We look for positive solutions and we do not assume that the reaction is nonnegative.

Nonlinear maximum principles for dissipative linear nonlocal operators and applications

open access: yes, 2011
We obtain a family of nonlinear maximum principles for linear dissipative nonlocal operators, that are general, robust, and versatile. We use these nonlinear bounds to provide transparent proofs of global regularity for critical SQG and critical d ...

Lipschitz regularity results for nonlinear strictly elliptic equations and applications

open access: yes, 2016
Most of lipschitz regularity results for nonlinear strictly elliptic equations are obtained for a suitable growth power of the nonlinearity with respect to the gradient variable (subquadratic for instance).

On the set of positive solutions for resonant Robin (p, q)-equations

open access: yesAdvances in Nonlinear Analysis, 2021
We consider a nonlinear Robin problem driven by the (p, q)-Laplacian and a parametric reaction exhibiting the competition of a concave term and of a resonant perturbation.
