A consistent intermediate wave speed for a well-balanced HLLC solver.
(Gauthier-Villars, 2008)
In this work, we present a HLLC scheme modification for application to nonhomogeneous shallow-water equations with pollutant transport. This new version is related to the definition of a consistent approximation of the ...

Finite element discretization of a Stokes-like model arising inplasma physics
(Elsevier, 2018)
We consider a time-dependent diffusion-reaction model for two vector unknowns, satisfying a divergence-free constraint, and the associated scalar Lagrange multiplier. The motivation for studying such a model is provided ...

Rectifications of A-Algebras
(2007)
In this article, in the setting of connected DG-modules, we prove that, for any A -algebra M mi i≥1 , there is a chain contraction from a DG-algebra AM onto the DG-module M such that the A -algebra structure induced ...

Strong Factorizations between Couples of Operators on Banach Function Spaces
(Heldermann Verlag, 2013)
Let T : X1 → Y1 and S : X2 → Y2 be two continuous linear operators between Banach function spaces related to a finite measure space. Under some lattice requirements on the spaces involved, we give characterizations by ...

A complete set of covariants of the four qubit system
(IOS Press, 2003)
We obtain a complete and minimal set of 170 generators for the algebra of SL(2, C )×4- covariants of a binary quadrilinear form. Interpreted in terms of a four qubit system, this describes in particular the algebraic ...

On a shallow water model for the simulation of turbidity currents
(Cambridge University Press, 2009)
We present a model for hyperpycnal plumes or turbidity currents that takes into account the interaction between the turbidity current and the bottom, considering deposition and erosion effects as well as solid transport ...

Solving the dynamic coloring problem for direct products of paths with fan graphs
(Sciendo, 2023-01)
This paper deals with the r-dynamic chromatic problem of the direct product of a path with a fan graph Fm,n. The problem is completely solved except for the case n < r ∈ {2m + 2, 2m + 3}, which is solved under certain ...
Article
Commutation and normal ordering for operators on symmetric functions
(2019)
We study the commutation relations and normal ordering between families of operators on symmetric functions. These operators can be naturally defined by the operations of multiplication, Kronecker product, and their ...

Quantum state-independent contextuality requires 13 rays
(IOP Science, 2016)
We show that, regardless of the dimension of the Hilbert space, there exists no set of rays revealing state-independent contextuality with less than 13 rays. This implies that the set proposed by Yu and Oh in dimension ...
