Non-uniqueness of global-in-time admissible weak solutions to the isentropic compressible Euler equations for a dense set of initial data

Daniel W. Boutros, Simon Markfelder

In recent years, the technique of convex integration has demonstrated that for some initial data (also referred to as 'wild initial data'), many PDE models of mathematical fluid me…

A Generalized Framework for Convex Integration and its Application to Geophysical Models

Daniel W. Boutros, Simon Markfelder, Edriss S. Titi

In this paper a general framework for convex integration is developed, in order to construct weak solutions to the Cauchy problem, by building on ideas from [C. De Lellis and L. Sz…

A mathematical study of an elastic-viscous-plastic sea-ice model with the Kelvin-Voigt rheology

Daniel W. Boutros, Xin Liu, Marita Thomas +1

Motivated by the elastic-viscous-plastic (EVP) sea-ice model [E. C. Hunke and J. K. Dukowicz, J. Phys. Oceanogr., 27, 9 (1997), 1849--1867], which is used in large-scale numerical…

Regularity thresholds for anomalous dissipation and related phenomena in passive scalars

Marco Bagnara, Daniel W. Boutros, Camillo De Lellis +1

We prove the absence of anomalous dissipation for passive scalars driven by some random autonomous divergence-free vector fields in . In dimension we just need c…

Global well-posedness of the elastic-viscous-plastic sea-ice model with the inviscid Voigt-regularisation

Daniel W. Boutros, Xin Liu, Marita Thomas +1

In this paper, we initiate the rigorous mathematical analysis of the elastic-viscous-plastic (EVP) sea-ice model, which was introduced in [E. C. Hunke and J. K. Dukowicz, J. Phys.…

On the absence of anomalous dissipation for the Navier-Stokes equations with Navier boundary conditions: a sufficient condition

Claude Bardos, Daniel W. Boutros, Edriss S. Titi

We consider the three-dimensional incompressible Navier-Stokes equations in a bounded domain with Navier boundary conditions. We provide a sufficient condition for the absence of a…
