Finiteness of cohomology groups of stacks of shtukas as modules over Hecke algebras, and applications [PDF]
Épijournal de Géométrie Algébrique, 2020 In this paper we prove that the cohomology groups with compact support of stacks of shtukas are modules of finite type over a Hecke algebra. As an application, we extend the construction of excursion operators, defined by V.

A note on spacelike and timelike compactness [PDF]
Class. Quantum Grav. 30 (2013) 115014, 2012 When studying the causal propagation of a field in a globally hyperbolic spacetime M, one often wants to express the physical intuition that it has compact support in spacelike directions, or that its support is a spacelike compact set.

Generalized control with compact support for systems with distributed parameters
Archives of Control Sciences, 2015 We propose a generalization of the Butkovskiy's method of control with compact support [1] allowing to derive exact controllability conditions and construct explicit solutions in control problems for systems with distributed parameters.

Support theorem on R^n and non compact symmetric spaces [PDF]
arXiv, 2010 We consider convolution equations of the type f * T = g where f, g are in L^p(R^n) and T is a compactly supported distribution. Under natural assumptions on the zero set of the Fourier transform of T we show that f is compactly supported, provided g is ...

Macroscopic and microscopic (non-)universality of compact support random matrix theory [PDF]
, 2000 A random matrix model with a σ-model like constraint, the restricted trace ensemble (RTE), is solved in the large-n limit. In the macroscopic limit the smooth connected two-point resolvent G(z,w) is found to be non-universal, extending previous results ...

The compact support property for measure-valued diffusions [PDF]
arXiv, 2004 The purpose of this article is to give a rather thorough understanding of the compact support property for measure-valued diffusion processes corresponding to semi-linear equations of the form \[& u_t=Lu+\beta u-\alpha u^p \text{in} R^d\times (0,\infty), p\in(1,2]; &u(x,0)=f(x) \text{in} R^d; &u(x,t)\ge0 \text{in} R^d\times[0,\infty). \] In particular,

European Physical Journal C: Particles and Fields, 2019 In a recent paper, Hod started a study on no scalar hair theorem for asymptotically flat spherically symmetric neutral horizonless reflecting compact stars. In fact, Hod's approach only rules out massive scalar fields.

A steady Euler flow with compact support [PDF]
Geometric and Functional Analysis, 2019 A nontrivial smooth steady incompressible Euler flow in three dimensions with compact support is constructed. Another uncommon property of this solution is the dependence between the Bernoulli function and the pressure.

Refinable Functions with Compact Support
Journal of Approximation Theory, 1996 AbstractIn this paper a refinable and blockwise polynomial with compact support is shown to be a finite linear combination of a box-spline and its translates (Theorems 1 and 2). Zak transform is used to give an upper bound for the regularity degree of a refinable function with compact support (Theorem 3).

Nef divisors for moduli spaces of complexes with compact support [PDF]
Selecta Mathematica, 2016 In [BM14b], the first author and Macr constructed a family of nef divisors on any moduli space of Bridgeland-stable objects on a smooth projective variety X. In this article, we extend this construction to the setting of any separated scheme Y of finite type over a field, where we consider moduli spaces of Bridgeland-stable objects on Y with compact ...
