Lim Ulrich sequences and Boij-Söderberg cones
Published 7 Sep 2022 in math.AC and math.AG | (2209.03498v2)
Abstract: This paper extends the results of Boij, Eisenbud, Erman, Schreyer, and S\"oderberg on the structure of Betti cones of finitely generated graded modules and finite free complexes over polynomial rings, to all finitely generated graded rings admitting linear Noether normalizations. The key new input is the existence of lim Ulrich sequences of graded modules over such rings.
