On a logarithmic version of the derived McKay correspondence
Sarah Scherotzke, Nicolò Sibilla, Mattia Talpo
We globalize the derived version of the McKay correspondence of Bridgeland-King-Reid, proven by Kawamata in the case of abelian quotient singularities, to certain log algebraic sta…
Logarithmic Picard groups, chip firing, and the combinatorial rank
Tyler Foster, Dhruv Ranganathan, Mattia Talpo +1
Illusie has suggested that one should think of the classifying group of -torsors on a logarithmically smooth curve over a standard logarithmic point as a logarithmic…
The Kato-Nakayama space as a transcendental root stack
Mattia Talpo, Angelo Vistoli
We give a functorial description of the Kato-Nakayama space of a fine saturated log analytic space that is similar in spirit to the functorial description of root stacks. As a cons…
The motivic class of the classifying stack of the special orthogonal group
Mattia Talpo, Angelo Vistoli
We compute the class of the classifying stack of the special orthogonal group in the Grothendieck ring of stacks, and check that it is equal to the multiplicative inverse of the cl…
