Parabolic sheaves with real weights as sheaves on the Kato-Nakayama space

Mattia Talpo

We define quasi-coherent parabolic sheaves with real weights on a fine saturated log analytic space, and explain how to interpret them as quasi-coherent sheaves of modules on its K…

A general formalism for logarithmic structures

Mattia Talpo, Angelo Vistoli

We extend the formalism of "log spaces" of arXiv:1507.06752 to topoi equipped with a sheaf of monoids, and discuss Deligne--Faltings structures and root stacks in this context.

On the motivic class of the classifying stack of $G_{2}$ and the spin groups

Roberto Pirisi, Mattia Talpo

We compute the class of the classifying stack of the exceptional algebraic group $G_{2}$ and of the spin groups $Spin_{7}$ and $Spin_{8}$ in the Grothendieck ring of st…
