MECHANICAL PROPERTIES OF GRANULITE FROM HORNÍ BORY IN BOHEMIAN MASSIF

open access: yesGeoScience Engineering, 2019
Granulite represents one of the favourite rock types for the construction of an underground nuclear waste repository in the Czech Republic. Granulite from the Bohemian Massif (locality Horní Bory) was investigated in this study, with a special focus on ...

Positively curved Killing foliations via deformations

open access: yes, 2018
We show that a compact manifold admitting a Killing foliation with positive transverse curvature fibers over finite quotients of spheres or weighted complex projective spaces, provided that the singular foliation defined by the closures of the leaves has

Influence of fault rock foliation on fault zone permeability: The case of deeply buried arkosic sandstones (Gres d'Annot, southeastern France)

open access: yes, 2013
We describe the structure, microstructure, and petrophysical properties of fault rocks from two normal fault zones formed in low-porosity turbiditic arkosic sandstones, in deep diagenesis conditions similar to those of deeply buried reservoirs.

Homotopy invariance of cohomology and signature of a riemannian foliation

open access: yes, 2017
We prove that any smooth foliation that admits a Riemannian foliation structure has a well-defined basic signature, and this geometrically defined invariant is actually a foliated homotopy invariant.

On the perfectness of C^{∞,s}-diffeomorphism groups on a foliated manifold [PDF]

open access: yesOpuscula Mathematica, 2008
The notion of \(C^{r,s}\) and \(C^{\infty,s}\)-diffeomorphisms is introduced. It is shown that the identity component of the group of leaf preserving \(C^{\infty,s}\)-diffeomorphisms with compact supports is perfect.
