Hölder foliations, revisited

open access: yesJournal of Modern Dynamics, 2012
We investigate transverse H lder regularity of some canonical leaf conjugacies in partially hyperbolic dynamical systems and transverse H lder regularity of some invariant foliations. Our results validate claims made elsewhere in the literature.

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 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.

Evaluation of vegetative phenological stages in a spruce monoculture depending on parameters of the environment

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2011
Vegetative phenological stages were evaluated in a spruce monoculture of the third age class in the region of the Drahanská vrchovina Upland. Methods of the ČHMÚ (Czech Hydro-Meteorological Office) were used. Temperature requirements of Norway spruce for

Varieties of complexes and foliations [PDF]

open access: yesJournal of Singularities, 2014
Let $\mathcal F(r, d)$ denote the moduli space of algebraic foliations of codimension one and degree $d$ in complex proyective space of dimension $r$. We show that $\mathcal F(r, d)$ may be represented as a certain linear section of a variety of complexes. From this fact we obtain information on the irreducible components of $\mathcal F(r, d)$.

Geology of amethyst quartz deposits from Montezuma and surrounding areas of Minas Gerais and Bahia States

open access: yesGeologia USP. Série Científica, 2023
Amethyst quartz deposits occur in some regions of Minas Gerais state, Brazil, related to different geological environments. The most important are associated with hydrothermal veins crossing the Espinhaço mountain range, mainly in small and eroded ...
