Non-commutative resolutions of linearly reductive quotient singularities
Christian Liedtke, Takehiko Yasuda
We prove existence of non-commutative crepant resolutions (in the sense of van den Bergh) of quotient singularities by finite and linearly reductive group schemes in positive chara…
F-blowups and essential divisors for toric varieties
Enrique Chávez-Martínez, Daniel Duarte, Takehiko Yasuda
We investigate the relation between essential divisors and F-blowups, in particular, address the problem whether all essential divisors appear on the -th F-blowup for large enou…
Open problems in the wild McKay correspondence and related fields
Takehiko Yasuda
The wild McKay correspondence is a form of McKay correspondence in terms of stringy invariants that is generalized to arbitrary characteristics. It gives rise to an interesting con…
On the behavior of stringy motives under Galois quasi-étale covers
Javier Carvajal-Rojas, Takehiko Yasuda
We investigate the behavior of stringy motives under Galois quasi-étale covers. We prove that they descend under such covers in a sense defined via their Poincaré realizations. Fur…
The Wild McKay Correspondence for Cyclic Groups of Prime Power Order
Mahito Tanno, Takehiko Yasuda
The -function is a key ingredient in the wild McKay correspondence. In this paper, we give a formula to compute it in terms of valuations of Witt vectors, when the…
Moduli of formal torsors II
Fabio Tonini, Takehiko Yasuda
Applying the authors' preceding work, we construct a version of the moduli space of -torsors over the formal punctured disk for a finite group . To do so, we introduce two Gr…
