On foliations of bounded mean curvature on closed three-dimensional Riemannian manifolds
Pracì Mìžnarodnogo Geometričnogo Centru, 2023 The notion of systole of a foliation sys(ℱ) on an arbitrary foliated closed Riemannian manifold (M,ℱ) is introduced. A lower bound on sys(ℱ) of a bounded mean curvature foliation is given.

Foliated vector bundles and Riemannian foliations [PDF]
Comptes Rendus. Mathématique, 2011 In this Note we prove the equivalence between the Riemannian foliation and each of the following conditions: 1) the lifted foliation Fr on the bundle of r-transverse jets is Riemannian for r⩾1; 2) the foliation F0r on the slashed J0r is Riemannian and vertically exact for r⩾1; 3) there exists a positively admissible transverse Lagrangian on J0rE, the r-

PETRO-MECHANICAL STUDIES OF THE STRATIGRAPHIC UNITS OF THE TARKWAIAN SUPERGROUP IN TARKWA – IMPLICATIONS FOR THE STRUCTURAL AND MECHANICAL COMPETENCE OF ROCKS [PDF]
Malaysian Journal of Geosciences, 2022 Main purpose of this paper is to determine the mineralogical composition and mechanical properties of the Tarkwaian Supergroup and compare them. This project will help determine whether the rock units of the Tarkwaian Supergroup are competent based on ...

Cosmological backreaction and its dependence on spacetime foliation [PDF]
Classical and quantum gravity, 2018 The subject of cosmological backreaction in general relativity is often approached by coordinate-dependent and metric-based analyses. We present in this letter an averaging formalism for the scalar parts of Einstein’s equations that is coordinate ...

Mixing properties and statistical limit theorems for singular hyperbolic flows without a smooth stable foliation [PDF]
Advances in Mathematics, 2017 Over the last 10 years or so, advanced statistical properties, including exponential decay of correlations, have been established for certain classes of singular hyperbolic flows in three dimensions.

Journal of Biomechanical Science and Engineering, 2021 The cerebellum has a unique morphology characterized by fine folds called folia. During cerebellar morphogenesis, folia formation (foliation) proceeds with granule cell (GC) proliferation in an external granular layer, and subsequent cell migration to an

Examples of foliations with foliated geometric structures [PDF]
Pacific Journal of Mathematics, 1990 We present examples of foliated compact nilmanifolds, whose foliations are neither simple nor given by suspensions, admitting various foliated geometric structures. For example, we construct foliations which are: 1. transversally symplectic but not transversally Kähler, 2. transversally symplectic but not transversally holomorphic, 3.

Bohmian Mechanics for a Degenerate Time Foliation [PDF]
, 2015 The version of Bohmian mechanics in relativistic space-time that works best, the hypersurface Bohm--Dirac model, assumes a preferred foliation of space-time into spacelike hypersurfaces (called the time foliation) as given.

Groups of basic automorphisms of chaotic Cartan foliations with Eresmann connection [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамикаThe purpose of the work is to study the groups of basic automorphisms of chaotic Cartan foliations with Ehresmann connection. Cartan foliations form a category where automorphisms preserve not only the foliation, but also its transverse Cartan geometry ...

On the inner automorphisms of a singular foliation [PDF]
Mathematische Zeitschrift, 2018 A singular foliation in the sense of Androulidakis and Skandalis is an involutive and locally finitely generated module of compactly supported vector fields on a manifold.
