Bulletin of the London Mathematical Society, Volume 58, Issue 6, June 2026.Abstract Given r⩾3$r \geqslant 3$, we prove that there exists λ>0$\lambda >0$ depending only on r$r$ so that if G$G$ is a metric graph of rank r$r$ with metric entropy 1, then there exists a proper subgraph H$H$ of G$G$ with metric entropy at least λ$\lambda$. This answers a question of the second two authors together with Rieck. We interpret this as a

Cohomogeneity‐one solitons in Laplacian flow: Local, smoothly‐closing and steady solitons
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract We initiate a systematic study of cohomogeneity‐one solitons in Bryant's Laplacian flow of closed G2$\text{G}_2$‐structures on a 7‐manifold, motivated by the problem of understanding finite‐time singularities of that flow. Here, we focus on solitons with symmetry groups Sp(2)${\rm Sp}(2)$ and SU(3)${\rm SU}(3)$; in both cases, we prove the ...

The Motion of Point Particles in Curved Spacetime
Living Reviews in Relativity, 2011 This review is concerned with the motion of a point scalar charge, a point electric charge, and a point mass in a specified background spacetime. In each of the three cases the particle produces a field that behaves as outgoing radiation in the wave zone,

An extended definition of Anosov representation for relatively hyperbolic groups
Journal of Topology, Volume 19, Issue 2, June 2026.Abstract We define a new family of discrete representations of relatively hyperbolic groups which unifies many existing definitions and examples of geometrically finite behavior in higher rank. The definition includes the relative Anosov representations defined by Kapovich–Leeb and Zhu, and Zhu–Zimmer, as well as holonomy representations of various ...

Analysis and Computation of Geodesic Distances on Reductive Homogeneous Spaces
Accepted Proceedings GSI LNCS 16034 (NB. In the published LNCS 16034 paper the Hamiltonian vector field associated to the Hamiltonian lack the over-right arrow, as there the LNCS compilation screwed up the standard \vec command, as result in the published LNCS paper the Hamiltonian vector fields have the same notation as the Hamiltonian)

Geodesic orbit and weak symmetric spray manifolds
In this paper, we introduce the geodesic orbit and weakly symmetric properties in homogeneous spray geometry. When a homogeneous spray manifold is endowed with a reductive decomposition, we can use the spray vector field to describe these properties, and

Homogeneous geodesics in five-dimensional generalized symmetric spaces
, 2002 O.Kowalski and J.Szenthe [7] proved that every homogeneous Riemannian manifold admits a homogeneous geodesic, that is, a geodesic which is an orbit of a one-parameter group of isometries.
