Compact support of spherically symmetric equilibria in non-relativistic and relativistic galactic dynamics [PDF]

open access: greenMathematical Proceedings of the Cambridge Philosophical Society, 2000
Equilibrium states in galactic dynamics can be described as stationary solutions of the Vlasov–Poisson system, which is the non-relativistic case, or of the Vlasov–Einstein system, which is the relativistic case.

Ultra-spinning exotic compact objects supporting static massless scalar field configurations

open access: yesPhysics Letters B, 2017
Horizonless spacetimes describing highly compact exotic objects with reflecting (instead of absorbing) surfaces have recently attracted much attention from physicists and mathematicians as possible quantum-gravity alternatives to canonical classical ...

Strong homology does not have compact supports

open access: bronzeTopology and its Applications, 1996
The paper exhibits examples of paracompact spaces $X$ with nonvanishing strong homology groups, while the (strong) homology groups with compact supports vanish. Moreover, all the ?ech homology groups of $X$ vanish.

The C*-Algebra Generated by Operators with Compact Support on a Locally Compact Group

open access: yesJournal of Functional Analysis, 1993
AbstractLet G be a locally compact group and VN(G) be the von Neumann algebra generated by the left regular representation of G. Let UCB(Ĝ) denote the C*-subalgebra generated by operators in VN(G) with compact support. When G is abelian, UCB(Ĝ) corresponds to the space of bounded uniformly continuous functions on the dual group Ĝ of G. In this paper we

Improved description of atomic environments using low-cost polynomial functions with compact support [PDF]

open access: yesMachine Learning: Science and Technology, 2020
The prediction of chemical properties using machine learning techniques calls for a set of appropriate descriptors that accurately describe atomic and, on a larger scale, molecular environments.

A Note on the Volume Conserving Solution to Simultaneous Aggregation and Collisional Breakage Equation

open access: yesAxioms, 2023
A new population balance model is introduced, in which a pair of particles can coagulate into a larger one if their encounter is a completely inelastic collision; otherwise, one of them breaks into multiple fragments (two or more) due to the elastic ...

Zeroes of Multifunctions with Noncompact Image Sets

open access: yesAxioms, 2023
In this article we consider zeroes for multifunctions with possibly noncompact image sets. We introduce the notion of multifunction with K-inf-compact support. We also establish three types of applications: the Bayesian approach for analysis of financial
