Stability of compact actions of the Heisenberg group
Tania M. Begazo, Nicolau C. Saldanha
Let G be the Heisenberg group of real lower triangular 3x3 matrices with unit diagonal. A locally free smooth action of G on a manifold M^4 is given by linearly independent vector…

Homotopy and cohomology of spaces of locally convex curves in the sphere
Nicolau C. Saldanha
We discuss the homotopy type and the cohomology of spaces of locally convex parametrized curves gamma: [0,1] -> S^2, i.e., curves with positive geodesic curvature. The space of all…

Nilpotent pseudogroups of functions on an interval
Tania M. Begazo, Nicolau C. Saldanha
A near-identity nilpotent pseudogroup of order m >= 1 is a family f_1, ..., f_n: (-1,1) -> R of C^2 functions for which: |f_i - id|_{C^1} < epsilon for some small positive real num…
