Contact Projective Structures [PDF]

open access: yesIndiana University Mathematics Journal, 2005
A contact projective structure is a contact path geometry the paths of which are among the geodesics of some affine connection. In the manner of T.Y.

Inferring epidemic contact structure from phylogenetic trees. [PDF]

open access: yesPLoS Computational Biology, 2012
Contact structure is believed to have a large impact on epidemic spreading and consequently using networks to model such contact structure continues to gain interest in epidemiology.

Contact structure on mixed links [PDF]

open access: yesVietnam Journal of Mathematics, 2012
A strongly non-degenerate mixed function has a Milnor open book structures on a sufficiently small sphere. We introduce the notion of {\em a holomorphic-like} mixed function and we will show that a link defined by such a mixed function has a canonical ...

Contact topology and the structure and dynamics of cholesterics

open access: yesNew Journal of Physics, 2017
Using tools and concepts from contact topology we show that non-vanishing twist implies conservation of the layer structure in cholesteric liquid crystals.

Contact and almost contact structures on the real extension of the Lobachevsky plane

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2021
In this article, we propose a group model G of a real extension of the Lobachevsky plane H2 × R . The group G is a Lie group of special-form matrices and a subgroup of the general linear group GL(3, R).

Partially integrable almost CR structures

open access: yesComplex Manifolds, 2021
Let (M, D) be a compact contact manifold with dimRM = 2n ≥ 5. This means that: M is a C∞ differential manifold with dimRM = 2n ≥ 5. And D is a subbundle of the tangent bundle TM which satisfying; there is a real one form θ such that D = {X : X ∈ TM, θ(X)

Global Geometry of Bayesian Statistics

open access: yesEntropy, 2020
In the previous work of the author, a non-trivial symmetry of the relative entropy in the information geometry of normal distributions was discovered. The same symmetry also appears in the symplectic/contact geometry of Hilbert modular cusps. Further, it

Bi-paracontact structures and Legendre foliations [PDF]

open access: yes, 2002
We study almost bi-paracontact structures on contact manifolds. We prove that if an almost bi-paracontact structure is defined on a contact manifold $(M,\eta)$, then under some natural assumptions of integrability, $M$ carries two transverse bi ...
