About the image of the total signature map in the two-dimensional case.
Clifford’s Theorem for real algebraic curves
We establish, for smooth projective real curves, an analogue of the classical Clifford inequality known for complex curves. We also study the cases when equality holds.
Normal forms of vector fields on Poisson manifolds
We study formal and analytic normal forms of radial and Hamiltonian vector fields on Poisson manifolds near a singular point.
Computations of Nambu-Poisson cohomologies.
