Martin Bauer, Alexey Boyarsky, Enrico Bertuzzo, Lesya Shchutska, Wenjing Wu, Karan Kumar, Francesco Cerutti, Wei Liu, Patrick Foldenauer, Yi Zhang, Saurabh Nangia, Raffaele Tito D'Agnolo, Emanuele Copello, Ji Hyun Kim, Yiming Li, Zheng Wang, Jing Li

High energy collisions at the High-Luminosity Large Hadron Collider (LHC) produce a large number of particles along the beam collision axis, outside of the acceptance of existing LHC experiments. The proposed Forward Physics Facility (FPF), to be located s ...

Feebly-Interacting Particles:FIPs 2020 Workshop Report

Martin Bauer, Alexey Boyarsky, Oleg Ruchayskiy, Lesya Shchutska, Marco Drewes

With the establishment and maturation of the experimental programs searching for new physics with sizeable couplings at the LHC, there is an increasing interest in the broader particle and astrophysics community for exploring the physics of light and feebl ...

Constructing reparameterization invariant metrics on spaces of plane curves

Martin Bauer, Martins Bruveris

Metrics on shape spaces are used to describe deformations that take one shape to another, and to define a distance between shapes. We study a family of metrics on the space of curves, which includes several recently proposed metrics, for which the metrics ...

Homogeneous Sobolev Metric of Order One on Diffeomorphism Groups on Real Line

Martin Bauer, Martins Bruveris

In this article we study Sobolev metrics of order one on diffeomorphism groups on the real line. We prove that the space equipped with the homogeneous Sobolev metric of order one is a flat space in the sense of Riemannian geometry, as it is isometric to an ...

Overview of the Geometries of Shape Spaces and Diffeomorphism Groups

Martin Bauer, Martins Bruveris

This article provides an overview of various notions of shape spaces, including the space of parametrized and unparametrized curves, the space of immersions, the diffeomorphism group and the space of Riemannian metrics. We discuss the Riemannian metrics th ...

Geodesic distance for right invariant Sobolev metrics of fractional order on the diffeomorphism group. II

Martin Bauer, Martins Bruveris

The geodesic distance vanishes on the group of compactly supported diffeomorphisms of a Riemannian manifold of bounded geometry, for the right invariant weak Riemannian metric which is induced by the Sobolev metric of order on the Lie algebra of vector fie ...

Geodesic distance for right invariant Sobolev metrics of fractional order on the diffeomorphism group

Martin Bauer, Martins Bruveris

We study Sobolev-type metrics of fractional order s a parts per thousand yen 0 on the group Diff (c) (M) of compactly supported diffeomorphisms of a manifold M. We show that for the important special case M = S (1), the geodesic distance on Diff (c) (S (1) ...
