A note on Chern-Weil classes of Cartan connections
Luca Accornero, Mateus M. de Melo, Ivan Struchiner
We present a construction of Chern-Weil characteristic classes for pairs Cartan geometries sharing the same underlying data. Given any model Cartan geometry with underlying…
The closure of linear foliations
Mateus de Melo, Ivan Struchiner
This paper presents a simplified geometric proof of the Molino-Alexandrino-Radeschi (MAR) Theorem, which states that the closure of a singular Riemannian foliation on a complete Ri…
The Classifying Lie Algebroid of a Geometric Structure II: G-structures with connection
Rui Loja Fernandes, Ivan Struchiner
Given a G-structure with connection satisfying a regularity assumption we associate to it a classifying Lie algebroid. This algebroid contains all the information about the equival…
Deformations of symplectic groupoids
Cristian Camilo Cárdenas, João Nuno Mestre, Ivan Struchiner
We describe the deformation cohomology of a symplectic groupoid, and use it to study deformations via Moser path methods, proving a symplectic groupoid version of the Moser Theorem…
Stability of Lie group homomorphisms and Lie subgroups
Cristian Camilo Cárdenas, Ivan Struchiner
We discuss a Moser type argument to show when a deformation of a Lie group homomorphism and of a Lie subgroup is trivial. For compact groups we obtain stability results.
Lie groupoids and semi-local models of Singular Riemannian foliations
Marcos M. Alexandrino, Marcelo K. Inagaki, Mateus de Melo +1
We describe a local model for any Singular Riemannian Foliation in a neighbourhood of a closed saturated submanifold of a regular stratum. Moreover we construct a Lie groupoid whic…
