Structural analysis of differentiated schists and gneisses in the Taalintehdas area, Kemiö Island, southwest Finland [PDF]

open access: yesBulletin of the Geological Society of Finland, 1980
Structural analysis of the Svecokarelic supracrustal schists and gneisses from around Taalintehdas, SW Kemiö Island, SW Finland, has been carried out and a preliminary interpretation is given of the regional structure of Kemiö Island in terms of the fold

Dimensional reduction to hypersurface of foliation [PDF]

open access: yes, 2013
When the bulk spacetime has a foliation structure, the collective dynamics of the hypersurfaces should reveal certain aspects of the bulk physics. The procedure of reducing the bulk to a hypersurface, called ADM reduction, was implemented in [3] where ...

Dynamics and the Godbillon-Vey Class of C^1 Foliations [PDF]

open access: yes, 2015
Let F be a codimension-one, C^2-foliation on a manifold M without boundary. In this work we show that if the Godbillon--Vey class GV(F) \in H^3(M) is non-zero, then F has a hyperbolic resilient leaf.

Entropy of foliations with leafwise Finsler structure

open access: yes, 2015
We extend the notion of the geometric entropy of foliation to foliated manifolds equipped with leafwise Finsler structure. We study the relation between the geometric entropy and the topological entropy of the holonomy pseudogroup.

Reduction of BTZ spacetime to hypersurfaces of foliation [PDF]

open access: yes, 2013
A bstractWe reduce the BTZ spacetime to two kinds of hypersurfaces of foliation: one having a fixed radial coordinate and the other a fixed angular coordinate. The radial reduction leads to a Liouville type theory, and confirms, from the first principle,

The Alpine Fault Hangingwall Viewed From Within: Structural Analysis of Ultrasonic Image Logs in the DFDP‐2B Borehole, New Zealand

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Ultrasonic image logs acquired in the DFDP‐2B borehole yield the first continuous, subsurface description of the transition from schist to mylonite in the hangingwall of the Alpine Fault, New Zealand, to a depth of 818 m below surface. Three feature sets

On holomorphic one-forms transverse to closed hypersurfaces

open access: yesAnais da Academia Brasileira de Ciências, 2003
In this note we announce some achievements in the study of holomorphic distributions admitting transverse closed real hypersurfaces. We consider a domain with smooth boundary in the complex affine space of dimension two or greater. Assume that the domain

Holonomy pseudogroups as obstructions to equivalence of manifolds over the algebra of dual numbers

open access: yesУчёные записки Казанского университета: Серия Физико-математические науки, 2019
A smooth manifold over the algebra of dual numbers D (a D-smooth manifold) carries the canonical foliation whose leaves are affine manifolds. Extension of charts on a D-smooth manifold along leaf paths allows ones to associate with an immersed ...

New insight into the Lectionary of Leipzig

open access: yesRasprave Instituta za Hrvatski Jezik i Jezikoslovlje, 2012
The paper presents new insight into the Lectionary of Leipzig (LL), a Cyrillic manuscript most probably dating from between 1560 and 1580. This insight primarily concern the results of an analysis of watermarks, which is particularly important as the ...
