Foliations by Curves with Curves as Singularities
Maurício Corrêa, Arturo Fernandez Perez, Gilcione Nonato Costa +1
Let be a holomorphic one-dimensional foliation on such that the components of its singular locus are curves and points . We determine the…
Torsion Free Sheaves on Cuspidal Curves
Dan Avritzer, Flaviana Andrea Ribeiro, Renato Vidal Martins
We study torsion free sheaves on integral projective curves with at most ordinary cusps as singularities. Adjusting Seshadri's structure from the nodal case to this one, we describ…
ADHM construction of perverse instanton sheaves
Abdelmoubine Amar Henni, Marcos Jardim, Renato Vidal Martins
We present a construction of framed torsion free instanton sheaves on a projective variety containing a fixed line which further generalizes the one on projective spaces. This is d…
