Variational discretization of the Navier-Stokes-Fourier system
Benjamin Couéraud, François Gay-Balmaz
This paper presents the variational discretization of the compressible Navier-Stokes-Fourier system, in which the viscosity and the heat conduction terms are handled within the var…
Variational discretization of thermodynamical simple systems on Lie groups
Benjamin Couéraud, François Gay-Balmaz
This paper presents the continuous and discrete variational formulations of simple thermodynamical systems whose configuration space is a (finite dimensional) Lie group. We follow…
Twisted cohomology of Lie algebroids
Benjamin Couéraud
In this short note we define a new cohomology for a Lie algebroid , that we call the \emph{twisted cohomology} of by an odd cocycle in the Lie algebr…
Dissections and automorphisms of regular Courant algebroids
Benjamin Couéraud
In this note, given a regular Courant algebroid, we compute its group of automorphisms relative to a dissection. We also propose an infinitesimal version and recover examples of th…
