Cotangent cohomology of quadratic monomial ideals
Amin Nematbakhsh
We study the deformation theory of quotients of polynomial rings by quadratic monomial ideals. More precisely we compute the first cotangent cohomology module of such rings. We als…
Rigid ideals by deforming quadratic letterplace ideals
Gunnar Fløystad, Amin Nematbakhsh
We compute the deformation space of quadratic letterplace ideals of finite posets when its Hasse diagram is a rooted tree. These deformations are unobstructed. The def…
Resolutions of letterplace ideals of posets
Alessio D'Alì, Gunnar Fløystad, Amin Nematbakhsh
We investigate resolutions of letterplace ideals of posets. We develop topological results to compute their multigraded Betti numbers, and to give structural results on these Betti…
Resolutions of co-letterplace ideals and generalizations of Bier spheres
Alessio D'Alì, Gunnar Fløystad, Amin Nematbakhsh
We give the resolutions of co-letterplace ideals of posets in a completely explicit, very simple form. This generalizes and simplifies a number of linear resolutions in the literat…
