Torsion subgroups and fixed-point rigidity in CAT(0) geometry
Jiankun Hou, Hiroyasu Izeki, Ran Ji +2
We develop new methods for studying groups acting on CAT(0) spaces, which lead to several general structural results. First, we prove that every torsion subgroup of a CAT(0) group…
The parametrix construction of the heat kernel on a graph
Gautam Chinta, Jay Jorgenson, Anders Karlsson +1
In this paper we develop the parametrix approach for constructing the heat kernel on a graph . In particular, we highlight two specific cases. First, we consider the case when $…
The resolvent kernel on the discrete circle and twisted cosecant sums
Jay Jorgenson, Anders Karlsson, Lejla Smajlović
Let denote the discrete circle with vertices. For and complex , let be the resolvent kernel associated to the combinatorial Laplaci…
The stars at infinity in several complex variables
Anders Karlsson
This text reviews certain notions in metric geometry that may have further applications to problems in complex geometry and holomorphic dynamics in several variables. The discussio…
Generalized Lyapunov exponents and aspects of the theory of deep learning
Anders Karlsson
We discuss certain recent metric space methods and some of the possibilities these methods provide, with special focus on various generalizations of Lyapunov exponents originally a…
Backward dynamics of non-expanding maps in Gromov hyperbolic metric spaces
Leandro Arosio, Matteo Fiacchi, Lorenzo Guerini +1
We study the interplay between the backward dynamics of a non-expanding self-map of a proper geodesic Gromov hyperbolic metric space and the boundary regular fixed points o…
