A Novel Regularity Criterion For The three-dimensional Navier-Stokes Equations Based On Finitely many observations

Abhishek Balakrishna, Animikh Biswas

In this paper we present two results: (1) A data assimilation algorithm for the 3D Navier-Stokes equation (3D NSE) using nodal data, and, as a consequence (2) a novel regularity cr…

Determining Map, Data Assimilation and an Observable Regularity Criterion for the Three-Dimensional Boussinesq System

Abhishek Balakrishna, Animikh Biswas

In this paper, we provide conditions, \emph{based solely on the observed velocity data}, for the global well-posedness, regularity and convergence of the Azouni-Olson-Titi data ass…

Data assimilation for the Navier-Stokes equations using local observables

Animikh Biswas, Zachary Bradshaw, Michael S. Jolly

We develop, analyze, and test an approximate, global data assimilation/synchronization algorithm based on purely local observations for the two-dimensional Navier-Stokes equations…

Space and time analyticity for inviscid equations of fluid dynamics

Animikh Biswas, Joshua Hudson

We show that solutions to a large class of inviscid equations, in Eulerian variables, extend as holomorphic functions of time, with values in a Gevrey class (thus space-analytic),…
