Uniformizable singular projective structures on Riemann surface orbifolds
Ahmed Elshafei, Julio C. Rebelo, Helena Reis
This paper is devoted to characterizing complex projective structures defined on Riemann surface orbifolds and giving rise to injective developing maps defined on the monodromy cov…
A remark on first integrals of vector fields
André Belotto da Silva, Martin Klimes, Julio C. Rebelo +1
We provide examples of vector fields on admitting a formal first integral but no holomorphic first integral. These examples are related to a question raised by…
Palais leaf-space manifolds and surfaces carrying holomorphic flows
Ana Cristina Ferreira, Julio C. Rebelo, Helena Reis
Starting from some remarkable singularities of holomorphic vector fields, we construct (open) complex surfaces over which the singularities in question are realized by complete vec…
Complete commuting vector fields and their singular points in dimension 2
Ana Cristina Ferreira, Julio C. Rebelo, Helena Reis
We classify degenerate singular points of $\C^2$-actions on complex surfaces.
Discrete orbits and special subgroups of $\Diff$
Julio C. Rebelo, Helena Reis
The local topological dynamics of subgroups of , with special emphasis on , is discussed with a view towards integrabi…
