On groups with locally compact asymptotic cones [PDF]

open access: greenInternational Journal of Algebra and Computation, 2013
We show how a recent result of Hrushovsky [Stable group theory and approximate subgroups, J. Amer. Math. Soc.25(1) (2012) 189–243] implies that if an asymptotic cone of a finitely generated group is locally compact, then the group is virtually nilpotent.

Asymptotic properties of PDEs in compact spaces [PDF]

open access: yesJournal of Fixed Point Theory and Applications, 2021
AbstractIn this article we combine the study of solutions of PDEs with the study of asymptotic properties of the solutions via compactification of the domain. We define new spaces of functions on which study the equations, prove a version of Ascoli–Arzelà Theorem, develop the fixed point index results necessary to prove existence and multiplicity of ...

Spectral asymptotics of compact pseudodifferential operators with ?constant? symbol [PDF]

open access: bronzeJournal of Soviet Mathematics, 1986
The author considers matrix pseudo-differential operators on Euclidean sets. It is supposed that this function of operator symbol belonging to the Hörmander class is the function with argument ''\(\xi\) ''. For these operators formula of spectral asymptotic with a remainder estimate is obtained.

Asymptotic distribution of functions on compact homogeneous spaces [PDF]

open access: bronzeAnnali di Matematica Pura ed Applicata, 1988
The authors study distribution properties of continuous functions on compact connected homogeneous Riemannian manifolds \(X\) (generalizing known results in the special case \(X=\mathbb{R}^n/\mathbb{Z}^n)\). It is proved that almost all functions are uniformly distributed and almost no functions are well distributed.

Asymptotic symmetries of projectively compact order one Einstein manifolds [PDF]

open access: bronzePhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences
We show that the boundary of a projectively compact Einstein manifold of dimension n can be extended by a line bundle naturally constructed from the projective compactification.

Asymptotic compactness in topological spaces [PDF]

open access: yesTopology and its Applications, 2021
The omega limit sets plays a fundamental role to construct global attractors for topological semi-dynamical systems with continuous time or discrete time. Therefore, it is important to know when omega limit sets become nonempty compact sets. The purpose of this paper is to understand the mechanism under which a given net of subsets of topological ...

Asymptotic invariants of lattices in locally compact groups [PDF]

open access: greenComptes Rendus. Mathématique, 2018
The aim of this work is to understand some of the asymptotic properties of sequences of lattices in a fixed locally compact group. In particular we will study the asymptotic growth of the Betti numbers of the lattices renormalized by the covolume and the rank gradient, the minimal number of generators also renormalized by the covolume.

Existence of pullback attractors for pullback asymptotically compact processes [PDF]

open access: greenNonlinear Analysis: Theory, Methods & Applications, 2009
This paper is concerned with the existence of pullback attractors for evolution processes. Our aim is to provide results that extend the following results for autonomous evolution processes (semigroups) i) An autonomous evolution process which is bounded dissipative and asymptotically compact has a global attractor.

Asymptotically optimal designs on compact algebraic manifolds [PDF]

open access: yesMonatshefte für Mathematik, 2018
We find t-designs on compact algebraic manifolds with a number of points comparable to the dimension of the space of polynomials of degree t on the manifold. This generalizes results on the sphere by Bondarenko, Radchenko and Viazovska. Of special interest is the particular case of the Grassmannians where our results improve the bounds that had been ...
