 Diagonal cyclic quotient singularity of order three

ID: diagonal-cyclic-quotient-singularity-of-order-three

The cone generated by

(1, 0)

and

(- 1, 3)

C [t_{2}, t_{1} t_{2}, t_{1}^{2} t_{2}, t_{1}^{3} t_{2}] ≅ C [x, y]^{μ_{3}},

where

μ_{3}

acts diagonally with weight one. Inserting the ray through

(0, 1)

resolves it, with one exceptional curve of self-intersection
