Point Modules of Non-Connected Graded Algebras
Thomas Lamkin
Source abstract
As part of a program to extend the homogeneous coordinate ring techniques of Artin-Tate-Van den Bergh to twisted graded Calabi-Yau (tCY) algebras, we initiate the study of point modules of non-connected graded algebras. We define weak and strong point modules of graded quotients of path algebras and compute their respective moduli stacks. We describe the relation between these point stacks and the classical point schemes in the connected graded setting, and we analyze the point stacks of several 2 and 3-dimensional tCY algebras.
