Lithium depletion and angular momentum transport in solar-type stars

T. Dumont, A. Palacios, C. Charbonnel +4

Transport processes occurring in the radiative interior of solar-type stars are evidenced by the surface variation of light elements, in particular Li, and the evolution of their r…

Gaia Early Data Release 3: The Gaia Catalogue of Nearby Stars

Gaia Collaboration, R. L. Smart, L. M. Sarro +420

We produce a clean and well-characterised catalogue of objects within 100\,pc of the Sun from the \G\ Early Data Release 3. We characterise the catalogue through comparisons to the…

Singular modules for affine Lie algebras, and applications to irregular WZNW conformal blocks

Giovanni Felder, Gabriele Rembado

We give a mathematical definition of spaces of irregular vacua/covacua in genus zero, for any simple Lie algebra, working at generic noncritical level. This uses coinvariants of af…

Vacuum Stability Conditions for Higgs Potentials with Triplets

Gilbert Moultaka, Michel C. Peyranère

Tree-level dynamical stability of scalar field potentials in renormalizable theories can in principle be expressed in terms of positivity conditions on quartic polynomial structure…

Separation of scales: Dynamical approximations for composite quantum systems

Irene Burghardt, Rémi Carles, Clotilde Fermanian Kammerer +2

We consider composite quantum-dynamical systems that can be partitioned into weakly interacting subsystems, similar to system-bath type situations. Using a factorized wave function…

K3 surfaces and cubic fourfolds with Abelian motive

Hanine Awada, Michele Bolognesi, Robert Laterveer +1

We show that cubic fourfolds with lattice of algebraic 2-cycles of rank greater than 19 have abelian and finite dimensional (in the sense of Kimura) Chow motive. This also implies…

Improved error estimates for Hybrid High-Order discretizations of Leray-Lions problems

Daniele Antonio Di Pietro, Jérôme Droniou, André Harnist

We derive novel error estimates for Hybrid High-Order (HHO) discretizations of Leray-Lions problems set in W^(1,p) with p in (1,2]. Specifically, we prove that, depending on the de…
