Nonlinear Spencer operators on differentiable groupoids
J. M. M. Veloso
We construct the first, second and sophisticated non-linear and linear Spencer complexes for a differentiable Lie groupoid . To do this, we extend the diagonal calculus, as appl…
Limit of Gaussian and normal curvatures of surfaces in Riemannian approximation scheme for sub-Riemannian three dimensional manifolds and Gauss-Bonnet theorem
Jose Veloso
The authors Balogh-Tyson-Vecchi in arXiv:1604.00180 utilize the Riemannian approximations scheme , in the Heisenberg group, introduced by Gromov, to calculate…
Rotation surfaces of constant Gaussian curvature as Riemannian approximation scheme in sub-Riemannian Heisenberg space
José M. M. Veloso
We verify if Gausssian curvature of surfaces and normal curvature of curves in surfaces introduced by Diniz-Veloso arXiv:1210.7110 and by Balogh-Tyson-Vecchi arXiv:1604.00180 to pr…
Flag structures on real 3-manifolds
E Falbel, J Veloso
We define flag structures on a real three manifold M as the choice of two complex lines on the complexified tangent space at each point of M. We suppose that the plane field define…
Gauss-Bonnet theorem in sub-Riemannian Heisenberg space
José M. M. Veloso, Marcos M. Diniz
We prove a version of Gauss-Bonnet theorem in sub-Riemannian Heisenberg space . The sub-Riemannian distance makes a metric space and consenquently with a spherical Hausd…
