Atlases for Ineffective Orbifolds
Dorette Pronk, Laura Scull, Matteo Tommasini
We give a definition of atlases for ineffective orbifolds, and prove that this definition leads to the same notion of orbifold as that defined via topological groupoids.
Weak fiber products in a bicategory of fractions
Matteo Tommasini
We fix any pair consisting of a bicategory and a class of morphisms in it, admitting a bicalculus of fractions, i.e. a "localization" of $\mathb…
Some insights on bicategories of fractions - III
Matteo Tommasini
We fix any bicategory together with a class of morphisms , such that there is a bicategory of fractions $\mathscr{A}[\mathbf{W}_{\mathscr{A}…

Matteo Tommasini
We fix any bicategory together with a class of morphisms , such that there is a bicategory of fractions $\mathscr{A}[\mathbf{W}_{\mathscr{A}…
Some insights on bicategories of fractions: representations and compositions of 2-morphisms
Matteo Tommasini
In this paper we investigate the construction of bicategories of fractions originally described by D. Pronk: given any bicategory together with a suitable class of mo…
A bicategory of reduced orbifolds from the point of view of differential geometry - I
Matteo Tommasini
We describe a bicategory of reduced orbifolds in the framework of classical differential geometry (i.e. without any explicit reference to notions o…
