Hölder Continuous Euler Flows in Three Dimensions with Compact Support in Time [PDF]

open access: yes, 2012
Motivated by the theory of turbulence in fluids, the physicist and chemist Lars Onsager conjectured in 1949 that weak solutions to the incompressible Euler equations might fail to conserve energy if their spatial regularity was below 1/3-Holder.

The Global Compact. Corporate Leadership in the World Economy

open access: yesSymphonya, 2002
United Nations Secretary-General Kofi Annan first proposed the Global Compact in an address to The World Economic Forum on the 31st January 1999. The Global Compact’s operational phase was launched at UN Headquarters in New York on the 26th July 2000 ...

Compact boson stars in K field theories

open access: yes, 2009
We study a scalar field theory with a non-standard kinetic term minimally coupled to gravity. We establish the existence of compact boson stars, that is, static solutions with compact support of the full system with self-gravitation taken into account ...

A note on the support of right invariant measures

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1992
A regular measure μ on a locally compact topological semigroup is called right invariant if μ(Kx)=μ(K) for every compact K and x in its support. It is shown that this condition implies a property reminiscent of the right cancellation law. This is used to

Global Well-posedness for 2D Nonlinear Wave Equations without Compact Support

open access: yes, 2017
In the significant work of [2], Alinhac proved the global existence of small solutions for 2D quasilinear wave equations under the null conditions. The proof heavily relies on the fact that the initial data have compact support [22].

Motion of Isolated bodies [PDF]

open access: yes, 2006
It is shown that sufficiently smooth initial data for the Einstein-dust or the Einstein-Maxwell-dust equations with non-negative density of compact support develop into solutions representing isolated bodies in the sense that the matter field has ...

No hair theorem for massless scalar fields outside asymptotically flat horizonless reflecting compact stars

open access: yesEuropean 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.

Spaces of non-additive measures generated by triangular norms

open access: yesМатематичні Студії, 2023
We consider non-additive measures on the compact Hausdorff spaces, which are generalizations of the idempotent measures and max-min measures. These measures are related to the continuous triangular norms and they are defined as functionals on the spaces ...

On Sobolev spaces and density theorems on Finsler manifolds [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2020
Here, a natural extension of Sobolev spaces is defined for a Finsler structure $F$ and it is shown that the set of all real $C^{\infty}$ functions with compact support on a forward geodesically complete Finsler manifold $(M, F),$ is dense in the extended
