Lim Ulrich序列与Boij-Söderberg锥
Lim Ulrich sequences and Boij-Söderberg cones
AI总结:
本文通过引入lim Ulrich序列,将Boij–Söderberg锥结构理论从多项式环推广到所有具有线性Noether正规化的有限生成分次环。
摘要:
本文将Boij、Eisenbud、Erman、Schreyer和Söderberg关于多项式环上有限生成分次模和有限自由复形的Betti锥结构的结果,推广到所有允许线性Noether正规化的有限生成分次环。关键的新输入是此类环上分次模的lim Ulrich序列的存在性。
英文摘要:
This paper extends the results of Boij, Eisenbud, Erman, Schreyer, and Söderberg 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.
