Degrees of Kalman varieties of tensors
Zahra Shahidi, Luca Sodomaco, Emanuele Ventura
Kalman varieties of tensors are algebraic varieties consisting of tensors whose singular vector -tuples lay on prescribed subvarieties. They were first studied by Ottaviani and…
Tensors with eigenvectors in a given subspace
Giorgio Ottaviani, Zahra Shahidi
The first author with B. Sturmfels studied the variety of matrices with eigenvectors in a given linear subspace, called Kalman variety. We extend that study from matrices to symmet…
The module of Valabrega-Valla of the Jacobian ideal of points in projective plane
Abbas Nasrollah Nejad, Zahra Shahidi
The module of Valabrega-Valla of the Jacobian ideal of a reduced projective variety is the torsion of the Aluffi algebra. One considers the problem of its vanishing in the case…
Torsion-free Aluffi Algebras
Abbas Nasrollah Nejad, Zahra Shahidi, Rashid Zaare-Nahandi
A pair of ideals has been called Aluffi torsion-free if the Aluffi algebra of is isomorphic with the corresponding Rees algebra. We give necessary a…
