Martingales on frame bundles
(SpringerDordrechtHolanda, 2008)
Fixed points on trivial surface bundles over a connected CW-complex
(2015-01-01)
The main purpose of this work is to study fixed points of fibre-preserving maps over a connected CW-complex B on the trivial surface bundles B×S where S is a closed surface of negative Euler characteristic. The case where ...
Differential geometry, Palatini gravity and reduction
(American Institute Of Physics, 2014-01)
The present article deals with a formulation of the so called (vacuum) Palatini gravity as a general variational principle. In order to accomplish this goal, some geometrical tools related to the geometry of the bundle of ...
Nahm transform for Higgs bundles

Using phylogenetic trees to generate semantic meaningful edge bundles
(Sociedade Brasileira de Computação - SBCUniversidade Federal da Bahia - UFBASalvador, 2015-08)
Graphs have been successfully applied in a range of problems and applications. It is the object of study of different areas, from modeling and analysis to the construction of visual representations. Different approaches ...
On the geometry of moduli spaces of anti-self-dual connections
(Elsevier Science BvAmsterdamHolanda, 2012)
Clustering of Whole-Brain White Matter Short Association Bundles Using HARDI Data
(2017)
Human brain connectivity is extremely complex and variable across subjects. While long association and projection bundles are stable and have been deeply studied, short association bundles present higher intersubject ...
Gauge structure of teleparallel gravity
(2019-06-01)
During the conference Teleparallel Universes in Salamanca, we became aware of a recent paper [M. Fontanini, E. Huguet, and M. Le Delliou, Phys. Rev. D 2019, 99, 064006] in which some criticisms on the interpretation of ...
