An Approach to Symbolic Regression Using Feyn

Autor: Broløs, Kevin René, Machado, Meera Vieira, Cave, Chris, Kasak, Jaan, Stentoft-Hansen, Valdemar, Batanero, Victor Galindo, Jelen, Tom, Wilstrup, Casper

In this article we introduce the supervised machine learning tool called Feyn. The simulation engine that powers this tool is called the QLattice. The QLattice is a supervised machine learning tool inspired by Richard Feynman's path integral formulat

Kirchberg--Wassermann exactness vs exactness: reduction to the unimodular totally disconnected case

Autor: Cave, Chris, Zacharias, Joachim

We show that in order to prove that every second countable locally compact groups with exact reduced group C*-algebra is exact in the dynamical sense (i.e. KW-exact) it suffices to show this for totally disconnected groups.

Exactness of locally compact groups

Autor: Brodzki, Jacek, Cave, Chris, Li, Kang

We give some new characterizations of exactness for locally compact second countable groups. In particular, we prove that a locally compact second countable group is exact if and only if it admits a topologically amenable action on a compact Hausdorf

Equivariant compression of certain direct limit groups and amalgamated free products

Autor: Cave, Chris, Dreesen, Dennis

We give a means of estimating the equivariant compression of a group G in terms of properties of open subgroups G_i whose direct limit is G. Quantifying a result by S.R. Gal, we also study the behaviour of the equivariant compression under amalgamate

Embeddability of generalized wreath products and box spaces

Autor: Cave, Chris, Dreesen, Dennis, Khukhro, Ana

Given two finitely generated groups that coarsely embed into a Hilbert space, it is known that their wreath product also embeds coarsely into a Hilbert space. We introduce a wreath product construction for general metric spaces X,Y,Z and derive a con

Embeddings of locally compact hyperbolic groups into Lp-spaces

Autor: Dreesen, Dennis, Cave, Chris

In the last years, there has been a large amount of research on embeddability properties of finitely generated hyperbolic groups. In this paper, we elaborate on the more general class of locally compact hyperbolic groups. We compute the equivariant $
