Weakly-exceptional quotient singularities in prime dimension

Sakovics, Dmitrijs

Original · EN

A singularity is said to be weakly-exceptional if it has a unique purely log terminal blow up. This is a natural generalization of the surface singularities of types Dₙ, E₆, E₇ and E₈. Since this idea was introduced, quotient singularities of this type have been classified in dimensions up to 5. This paper looks at such singularities in dimension p, where p is an arbitrary prime number.
