Newton–Okounkov Bodies of Exceptional Curve Plane Valuations Non-positive at Infinity
Springer (2018-11-04)In this note we announce a result determining the Newton–Okounkov bodies of the line bundle OP2(1) with respect to exceptional curve plane valuations non-positive at infinity. -
On the computation of Darboux first integrals of a class of planar polynomial vector fields
Elsevier (2019-05)We study the class of planar polynomial vector fields admitting Darboux first integrals of the type I I r i=1 fiαi , where the αi 's are positive real numbers and the fi 's are polynomials defining curves with only one ...

On the Degree of Curves with Prescribed Multiplicities and Bounded Negativity
Oxford University Press (2022-07-28)We provide a lower bound on the degree of curves of the projective plane P2 passing through the centers of a divisorial valuation ν of P2 with prescribed multiplicities, and an upper bound for the Seshadri-type constant ...

The Poincaré Polynomial of a Linear Code
Springer (2018-09-19)We introduce the Poincaré polynomial of a linear q-ary code and its relation to the corresponding weight enumerator. The question of whether the Poincaré polynomial is a complete invariant is answered affirmatively for ...

The Poincaré problem, algebraic integrability and dicritical divisors
(2015-07-01)We solve the Poincaré problem for plane foliations with only one dicritical divisor. Moreover, in this case, we give a simple algorithm that decides whether a foliation has a rational first integral and computes it in the ...
