Holomorphic foliations of degree two and arbitrary dimension

M Corrêa, A Muniz - arXiv preprint arXiv:2207.12880, 2022 - arxiv.org
Let $\mathscr {F} $ be a holomorphic foliation of degree $2 $ on $\mathbb {P}^ n $ with
dimension $ k\geq 2$. We prove that either $\mathscr {F} $ is algebraically integrable, or …

Moduli of distributions via singular schemes

M Corrêa, M Jardim, A Muniz - Mathematische Zeitschrift, 2022 - Springer
Let X be a smooth projective variety. We show that the map that sends a codimension one
distribution on X to its singular scheme is a morphism from the moduli space of distributions …

[PDF][PDF] Classification of foliations by curves of low degree on the three-dimensional projective space

M Corrêa, M Jardim, S Marchesi - arXiv preprint arXiv:1909.06590, 2020 - researchgate.net
We study foliations by curves on the three-dimensional projective space with no isolated
singularities, which is equivalent to assuming that the conormal sheaf is locally free. We …

This paper is devoted to the study of holomorphic distributions of dimension and
codimension one on smooth weighted projective complete intersection Fano manifolds X …

Enumerative geometry of Legendrian foliations: a tale of contact

M Corrêa, I Vainsencher - arXiv preprint arXiv:2209.12085, 2022 - arxiv.org
A contact distribution on projective three-space is defined by the 1-form $ x_2dx_1-
x_1dx_2+ x_4dx_3-x_3dx_4 $, up to a change of projective coordinates. The family of …

Analytic Varieties Invariant by Holomorphic Foliations and Pfaff Systems

M Corrêa - Handbook of Geometry and Topology of Singularities …, 2024 - Springer
In this work we shall present a survey on problems and results on singular holomorphic
foliations and Pfaff systems on complex manifolds assuming that these objects possess …

Non-Ulrich representation type

D Faenzi, F Malaspina, G Sanna - arXiv preprint arXiv:1907.02694, 2019 - arxiv.org
We show that a smooth projective non-degenerate arithmetically Cohen-Macaulay
subvariety X of P^ N infinite Cohen-Macaulay type becomes of finite Cohen-Macaulay type …

Inequalities and enumerative formulas for flags of Pfaff systems

MR Peña, F Lourenço - arXiv preprint arXiv:2401.17208, 2024 - arxiv.org
In this work, we study inequalities and enumerative formulas for flags of Pfaff systems on
$\mathbb {P}^ n_ {\mathbb {C}} $. More specifically, we find the number of independent Pfaff …
