Generalized transversely projective structure on a transversely holomorphic foliation

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2002
The results of Biswas (2000) are extended to the situation of transversely projective foliations. In particular, it is shown that a transversely holomorphic foliation defined using everywhere locally nondegenerate maps to a projective space ℂℙn, and ...

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

Spherical spacelike geometries in static spherically symmetric spacetimes: Generalized Painlevè–Gullstrand coordinates, foliation, and embedding

open access: yesPhysics Letters B, 2017
It is well known that static spherically symmetric spacetimes can admit foliations by flat spacelike hypersurfaces, which are best described in terms of the Painlevè–Gullstrand coordinates.

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 ...
