TL;DR: In this article, the authors show how recent results on the theory of quasi-stationary distributions allow to deduce effortlessly general criteria for the geometric convergence of normalized unbounded semigroups.

TL;DR: In this paper, the authors prove a Macdonald's formula for the image of a basis element of a spherical Hecke algebra over a local non-archimedean field.
Abstract: For an almost split Kac-Moody group G over a local non-archimedean field, the last two authors constructed a spherical Hecke algebra H (over the complex numbers C, say) and its Satake isomorphism with the commutative algebra of Weyl invariant elements in some formal series algebra C[[Y]].In this article, we prove a Macdonald's formula, i.e. an explicit formula for the image of a basis element of H. The proof involves geometric arguments in the masure associated to G and algebraic tools, including the Cherednik's representation of the Bernstein-Lusztig-Hecke algebra (introduced in a previous article) and the Cherednik's identity between some symmetrizers.

TL;DR: In this article, the authors investigate the relation between representations of dimension finie des algebres de Lie en rapport with representations of sous-representations of dimension 2.
Abstract: Dans une premier temps nous etudions les representations de dimension finie des algebres de Lie en rapport avec le treillis des sous-representations. Nous considerons le cas ou la representation laisse invariant deux paires de sous-espaces supplementaires. Nous montrons que la representation peut etre decomposee dans ce cas en une somme de trois sous-representations canoniques que nous caracterisons. Nous precisons les resultats dans le cas d'une representation preservant deux sous-espaces supplementaires et une forme reflexive, et aussi dans le cas metrique. Dans une deuxieme partie geometrique nous appliquons les resultats precedents a l'etude des representations d'holonomie d'une variete munie d'une connexion sans torsion ou en particulier reflexive ou pseudo-Riemannienne. Enfin nous examinons de plus pres les representations de type somme directe de V et V dual , respectivement V tenseur la representation triviale de dimension 2 , qui apparaissent dans le cadre de cette etude, et nous caracterisons les connexions sans torsion admettant une telle representation d'holonomie.

TL;DR: An energy-conserving split-step Pade method for their numerical solution is developed and several examples are considered including the propagation of sound in a perfect wedge, a whispering gallery formation near circular is obath, and the breaking of the whispering gallery waveguide in the vicinity of an inflection point of the isobath.

TL;DR: This paper constructs a self-financing strategy that minimizes the CVaR of hedging risk under a budget constraint on the initial capital and applies the Neyman-Pearson lemma approach with a specific equivalent martingale measure to approximate the problem.
