Mass formulas and stringy point-count for semi-direct products of tame abelian groups and wild symmetric or cyclic groups in characteristic three
Takahiro Yamamoto
In positive characteristic, there exist counterexamples to the statement corresponding to Batyrev's theorem concerning the McKay correspondence. In this paper, we give another comp…
The v-function in the wild McKay correspondence is not determined by the ramification filtration
Takahiro Yamamoto
The \(v\)-function appears in the wild McKay correspondence and it is an invariant of a Galois extension over a local field which measures about the ramification of extension. The…
Crepant resolutions of quotient varieties in positive characteristics and their Euler characteristics
Takahiro Yamamoto
In characteristic zero, if a quotient variety has a crepant resolution, the Euler characteristic of the crepant resolution is equal to the number of conjugacy classes of the acting…
Pathological quotient singularities in characteristic three which are not log canonical
Takahiro Yamamoto
In characteristic zero, quotient singularities are log terminal. Moreover, we can check whether a quotient variety is canonical or not by using only the age of each element of the…
