摘要：Let $A$ be a Noetherian $\mathbb N$-graded algebra. Let $gr A$ be the category of finitely generated right graded $A$-modules and let $tors A$ be the full subcategory of $gr A$ consisting of finite dimensional modules. The quotient category $qgr A:=gr A/tors A$ is a noncommutative analogue of projective schemes. If $qgr A$ has finite global dimension, then $A$ is called a noncommutative graded isolated singularity. In this talk, I will give a brief survey of the progress in the last decade.
