Some composition determinants
J. M. Brunat, C. Krattenthaler, A. Lascoux +1
We compute two parametric determinants in which rows and columns are indexed by compositions, where in one determinant the entries are products of binomial coefficients, while in t…
Quantitative Spectroscopy of Supernovae for Dark Energy Studies
E. Baron, David Branch, David Jeffery +6
Detailed quantitative spectroscopy of Type Ia supernovae (SNe~Ia) provides crucial information needed to minimize systematic effects in both ongoing SNe Ia observational programs s…
Two-dimensional incompressible viscous flow around a small obstacle
D. Iftimie, M. C. Lopes Filho, H. J. Nussenzveig Lopes
In this work we study the asymptotic behavior of viscous incompressible 2D flow in the exterior of a small material obstacle. We fix the initial vorticity and the circulation…
The -triangle of the generalised cluster complex
Christian Krattenthaler
The -triangle is a refined face count for the generalised cluster complex of Fomin and Reading. We compute the -triangle explicitly for all irreducible finite root systems. F…
The magnetic structure of neutron stars and their surface-to-core temperature relation
A. Y. Potekhin, V. Urpin, G. Chabrier
We study the relation between the mean effective surface temperature T_s and the internal temperature T_b for magnetic neutron stars, assuming that the magnetic field near the surf…
Demonstration de la conjecture de Dumont
Bodo Lass
Dumont has conjectured a marvellous identity, which generalizes, in particular, the classical results of Lagrange, Gauss, Jacobi and Kronecker on the sums of two, three and four sq…
