Jacobian Ideals of Hyperplane Arrangements and their Graded Betti Numbers

Juan Migliore, Uwe Nagel

A hyperplane arrangement $\cA$ is said to be free if the corresponding Jacobian ideal $J_\cA$ is Cohen-Macaulay. If $\cA$ is free then $J_\cA$ is unmixed (i.e. equidimensional). Fr…

On the Weak Lefschetz Property for certain ideals generated by powers of linear forms

Giuseppe Favacchio, Juan Migliore

Ideals generated by powers of linear forms arise, via Macaulay duality, from sets of fat points . Properties of are conn…

The weak Lefschetz property for artinian Gorenstein algebras of small Sperner number

Mats Boij, Juan C. Migliore, Rosa Maria Miró-Roig +1

For artinian Gorenstein algebras in codimension four and higher, it is well known that the Weak Lefschetz Property (WLP) does not need to hold. For Gorenstein algebras in codimensi…

Geproci sets on skew lines in with two transversals

Luca Chiantini, Pietro De Poi, Lucja Farnik +6

The purpose of this work is to pursue classification of geproci sets. Specifically we classify -geproci sets which consist of points on each of skew lines, assumin…

Jacobian schemes arising from hypersurface arrangements in

Juan Migliore, Uwe Nagel

Freeness is an important property of a hypersurface arrangement, although its presence is not well understood. A hypersurface arrangement in $\PP^n$ is free if is Cohen-Macau…

Combinatorics of skew lines in with an application to algebraic geometry

Luca Chiantini, Łucja Farnik, Giuseppe Favacchio +4

This article introduces a previously unrecognized combinatorial structure underlying configurations of skew lines in , and reveals its deep and surprising connection…
