Weak subordination of multivariate Lévy processes »
In our simulations, we find that maximum likelihood produces a better fit when a Fourier invertibility condition holds, while digital moment estimation produces a better fit when it doesn't.
Mutation in populations governed by a Galton-Watson branching process »
In this talk I will describe a multi-type branching process, in which the population is divided into a finite number of allele types.
Perverse sheaves on hyperplane arrangements and gluing »
I'll describe the analogue on the quiver side of the natural gluing, or "recollement", structure of this category of perverse sheaves.
Introduction to Cohomology, III »
I'll continue the introduction to cohomology with more about group cohomology and Galois cohomology.
Localising modules, rings, and spectra. »
Given a ring R and a multiplicative subset S of R, then one can localise R at S using a number of different constructions.
Intro to and examples of (>1)- categories »
The PhD seminar is a weekly seminar held on Tuesday mornings, at 11am, for PhD students to talk about their thesis work or other projects.
Khovanov homology for links in thickened surfaces and a categorification of the skein algebra multiplication, part 2 »
(Continuation of talk from February 9)
Introduction to Cohomology, II »
I'll continue the introduction to cohomology with group cohomology and Galois cohomology.
Modular representation theory via categorification and knot theory »
We will study the category of modular representations of the special linear Lie algebra in positive characteristic; we focus on the case with a central Frobenius character given by a nilpotent whose Jordan type is a two-row partition.
Developing euclidean domains and the isomorphism theorems for groups in Lean, an interactive theorem prover »
Summer ASC students Louis Carlin and Mitchell Rowett will describe their experience developing mathematical libraries for Lean, a new interactive theorem prover.
