Permanence of metric fractals

Electronic Journal of Differential Equations, 2007
The paper studies energy functionals on quasimetric spaces, defined by quadratic measure-valued Lagrangeans. This general model of medium, known as metric fractals, includes nested fractals and sub-Riemannian manifolds.

Mean-square continuity on homogeneous spaces of compact groups [PDF]

, 2012
We show that any finite-variance, isotropic random field on a compact group is necessarily mean-square continuous, under standard measurability assumptions.

Homogeneous ANR-spaces and Alexandroff manifolds

, 2014
We specify a result of Yokoi \cite{yo} by proving that if $G$ is an abelian group and $X$ is a homogeneous metric $ANR$ compactum with $\dim_GX=n$ and $\check{H}^n(X;G)\neq 0$, then $X$ is an $(n,G)$-bubble.

Intertwining Operators And Quantum Homogeneous Spaces

, 1995
In the present paper the algebras of functions on quantum homogeneous spaces are studied. The author introduces the algebras of kernels of intertwining integral operators and constructs quantum analogues of the Poisson and Radon transforms for some ...

Ancient solutions of the homogenous Ricci flow on flag manifolds

Extracta Mathematicae, 2021
For any flag manifold M=G/K of a compact simple Lie group G we describe non-collapsing ancient invariant solutions of the homogeneous unnormalized Ricci flow.

Controllability of Bilinear Systems: Lie Theory Approach and Control Sets on Projective Spaces

Mathematics
Bilinear systems can be developed from the point of view of time-varying linear differential equations or from the symmetry of Lie theory, in particular Lie algebras, Lie groups, and Lie semigroups. For bilinear control systems with bounded control range,

Brascamp–Lieb Inequalities on Compact Homogeneous Spaces

Analysis and Geometry in Metric Spaces, 2019
We provide a general strategy to construct multilinear inequalities of Brascamp–Lieb type on compact homogeneous spaces of Lie groups. As an application we obtain sharp integral inequalities on the real unit sphere involving functions with some degree of

Quantum Homogeneous Spaces and Coalgebra Bundles

, 1997
It is shown that quantum homogeneous spaces of a quantum group H can be viewed as fibres of quantum fibrations with the total space H that are dual to coalgebra bundles. As concrete examples of such structures the fibrations with the quantum 2-sphere and

A classification of Poisson homogeneous spaces of complex reductive Poisson-Lie groups

, 2000
Let $G$ be a complex reductive connected algebraic group equipped with the Sklyanin bracket. A classification of Poisson homogeneous $G$-spaces with connected isotropy subgroups is given.
