On Some Transverse Geometrical Structures of Lifted Foliation to Its Conormal Bundle

open access: yesThe Scientific World Journal, 2015
We consider the lift of a foliation to its conormal bundle and some transverse geometrical structures associated with this foliation are studied. We introduce a good vertical connection on the conormal bundle and, moreover, if the conormal bundle is ...

Abnormal struktur histologis korteks cerebellar tikus dengan normal foliasi akibat iradiasi sinar X masa postnatal

open access: yesJournal of Biological Researches, 2012
Our previous experiment showed that prenatal exposure of rats to X-irradiation on gestation day 21st as the late gestation period causes heterotopic Purkinje cells and abnormal foliation of the cerebellum.

Foliations in supergravity [PDF]

open access: yesThe Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1999
AbstractFollowing upon a previous paper [1] on the existence of chiral transformations in a foliated version of the Cremmer, Julia and Scherk model, we deduce a couple of interesting properties of the model. These are:(i) TM4 is isomorphic to a quotient Lie pseudoalgebra on the algebra of basic functions in M11;(ii) There is a locally trivial fibration

Characteristic foliation on a hypersurface of general type in a projective symplectic manifold

open access: yes, 2008
Given a projective symplectic manifold $M$ and a non-singular hypersurface $X \subset M$, the symplectic form of $M$ induces a foliation of rank 1 on $X$, called the characteristic foliation.

On transversely holomorphic foliations with homogeneous transverse structure

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2023
In this paper we study transversely holomorphic foliations of complex codimension one with a transversely homogeneous complex transverse structure. We prove that the only cases are the transversely additive, affine and projective cases. We shall focus on

Surgery on Foliations

open access: yes, 2022
In this paper, we set up two surgery theories and two kinds of Whitehead torsion for foliations. First, we construct a bounded surgery theory and bounded Whitehead torsion for foliations, which correspond to the Connes' foliation algebra in the K-theory of operator algebras, in the sense that there is an analogy between surgery theory and index theory,

Foliations with non-compact leaves on surfaces

open access: yesPracì Mìžnarodnogo Geometričnogo Centru, 2020
The paper studies non-compact surfaces obtained by gluing strips R × (−1, 1) with at most countably many boundary intervals along some of these intervals.

On the smoothness of Levi-foliations [PDF]

open access: yesPublicacions Matemàtiques, 1988
We study the regularity of the induced foliation of a Levi-flat hypersurface in C'°, showing that the foliation is as many times continuously differentiable as the hypersurface itself. The key step in the proof given here is the construction of a certain family of approximate plurisubharmonic defining functions for the hypersurface in question.

Embedded curves and foliations [PDF]

open access: yesPublicacions Matemàtiques, 2011
We prove the existence of regular foliations with a prescribed tangency divisor in neighborhoods of negatively embedded holomorphic curves; this is related to a linearization theorem due to Grauert. We give also examples of neighborhoods which can not be linearized.

Classical and Quantum Dynamics on Orbifolds

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
We present two versions of the Egorov theorem for orbifolds. The first one is a straightforward extension of the classical theorem for smooth manifolds.
