Castelnuovo-Mumford regularity of deficiency modules

Markus Brodmann, Maryam Jahangiri, Cao Huy Linh

Hilbert scheme strata defined by bounding cohomology

Stefan Fumasoli

Let Hilb^p be the Hilbert scheme parametrizing the closed subschemes of P^n with Hilbert polynomial p\in Q[t] over a field K of characteristic zero. By bounding below the cohomolog…

On varieties of almost minimal degree in small codimension

Markus Brodmann, Peter Schenzel

The aim of the present exposition is to investigate varieties of almost minimal degree and of low codimension, in particular their Betti diagrams. Here minimal degree is defined as…

Arithmetic properties of projective varieties of almost minimal degree

Markus Brodmann, Peter Schenzel

We study the arithmetic properties of projective varieties of almost minimal degree, that is of non-degenerate irreducible projective varieties whose degree exceeds the codimension…

Associated primes of graded components of local cohomology modules

Markus P. Brodmann, Mordechai Katzman, Rodney Y. Sharp

The -th local cohomology module of a finitely generated graded module over a standard positively graded commutative Noetherian ring , with respect to the irrelevant ideal…
