Higher traces, noncommutative motives, and the categorified Chern character
Marc Hoyois, Sarah Scherotzke, Nicolò Sibilla
We propose a categorification of the Chern character that refines earlier work of Toën and Vezzosi and of Ganter and Kapranov. If X is an algebraic stack, our categorified Chern ch…
Kato-Nakayama spaces, infinite root stacks, and the profinite homotopy type of log schemes
David Carchedi, Sarah Scherotzke, Nicolò Sibilla +1
For a log scheme locally of finite type over , a natural candidate for its profinite homotopy type is the profinite completion of its Kato-Nakayama space. Alternatively…
Quiver varieties and Hall algebras
Sarah Scherotzke, Nicolo Sibilla
In this paper we give a geometric construction of the quantum group Ut(G) using Nakajima categories, which were developed in [29]. Our methods allow us to establish a direct connec…
Derived loop stacks and categorification of orbifold products
Sarah Scherotzke, Nicolò Sibilla
The existence of interesting multiplicative cohomology theories for orbifolds was first suggested by string theorists. Orbifold products have been intensely studied by mathematicia…
