The moduli space of torsion-free sheaves with quasi-maximal third Chern class
Charles Almeida, Marcos Jardim, Leonardo Oliveira
In this paper, we investigate the geometry of the Gieseker moduli space of semistable rank torsion-free sheaves on with Chern classes $(c_1, c_2, c_3) = (-1, c_2…
The Bourbaki degree of the syzygy module of 2 4 matrices
Marcos Jardim, Felipe Monteiro, Abbas Nasrollah Nejad
We introduce and study the Bourbaki degree as a numerical invariant for \(2 \times 4\) matrices of homogeneous polynomials over a polynomial ring \(R = k[x_1, \dots, x_n]\). Th…
The Bourbaki Degree of Plane Projective Curves
Marcos Jardim, Abbas Nasrollah Nejad, Aron Simis
Bourbaki sequences and Bourbaki ideals have been studied by several authors since its inception sixty years ago circa. Generic Bourbaki sequences have been thoroughly examined by t…
Instantons: the next frontier
Gaia Comaschi, Marcos Jardim, Cristian Martinez +1
Instantons, emerged in particle physics, have been intensely studied since the 1970's and had an enormous impact in mathematics since then. In this paper, we focus on one particula…
Instanton sheaves on Fano threefolds
Gaia Comaschi, Marcos Jardim
Generalizing the definitions originally presented by Kuznetsov and Faenzi, we study (possibly non locally free) instanton sheaves of arbitrary rank on Fano threefolds. We classify…
Vertical asymptotics for Bridgeland stability conditions on 3-folds
Marcos Jardim, Antony Maciocia, Cristian Martinez
Let be a smooth projective threefold of Picard number one for which the generalized Bogomlov-Gieseker inequality holds. We characterize the limit Bridgeland semistable objects…
