Math AnnAbstract We present an adjunction formula for foliations on varieties and we consider applications of the adjunction formula to the cone theorem for rank one foliations and the study of foliation singularities.

Approximation of Foliations [PDF]
Canadian Mathematical Bulletin, 1971 Let be two foliations on a Cr manifold M. We say and are Ck-conjugate if there exists a Ck diffeomorphism h:M→M such that h maps the leaves of onto the leaves of .

TRANSCRIPTION FACTORS IN CEREBELLAR DEVELOPMENT [PDF]
Trakia Journal of Sciences, 2023 The cerebellar germ arises from the rhombic lip, and it’s a rostral part from the mesencephalon. The following cellular processes take place in the developing cerebellum: proliferation, migration, differentiation, synapse formation and cell death.

Integral Formulas for a Foliation with a Unit Normal Vector Field
Mathematics, 2021 In this article, we prove integral formulas for a Riemannian manifold equipped with a foliation F and a unit vector field N orthogonal to F, and generalize known integral formulas (due to Brito-Langevin-Rosenberg and Andrzejewski-Walczak) for foliations ...

Advances in Civil Engineering, 2021 In this study, the continuum-discontinuum element method (CDEM) was used to investigate the tensile fracture mechanism of rock materials. An isotropic rock disk model and models considering different foliation inclinations were established, and three ...

Holomorphic foliations and deformations of the Hopf foliation [PDF]
Pacific Journal of Mathematics, 1984 A deformation theory for transversally holomorphic foliations is developed here and used to give an explicit description of the transver- sally holomorphic foliations near the "Hopf foliations" on odd dimen- sional spheres. Introduction. In (1) and (2) we began the study of the deformation theory of holomorphic foliations on a smooth compact manifold ...

STRUCTURES OF BIRIMIAN AND TARKWAIAN ROCKS AT NORTH-WEST NEW DROBO – IMPLICATION ON DEFORMATION [PDF]
Malaysian Journal of Geosciences, 2022 This research leads to identifying the microstructures, the deformation episodes (D) and foliation grades (S) of rocks in the study area. Different geological structures such as shear zones, foliations, micro-faults, crack-seal events, etc.

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.

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-
