Persistence of invariant manifolds for perturbations of semiflows with symmetry
Electronic Journal of Differential Equations, 1999 Consider a semiflow in a Banach space, which is invariant under the action of a compact Lie group. Any equilibrium generates a manifold of equilibria under the action of the group.

Sigma models with negative curvature
Physics Letters B, 2016 We construct Higgs Effective Field Theory (HEFT) based on the scalar manifold Hn, which is a hyperbolic space of constant negative curvature. The Lagrangian has a non-compact O(n,1) global symmetry group, but it gives a unitary theory as long as only a ...

The genus spectrum of a hyperbolic 3-manifold [PDF]
, 2009 In this article we study the spectrum of totally geodesic surfaces of a finite volume hyperbolic 3-manifold. We show that for arithmetic hyperbolic 3-manifolds that contain a totally geodesic surface, this spectrum determines the commensurability class ...

Multifunctional Fluidic Units for Emergent, Responsive Robotic Behaviors
Advanced Materials, EarlyView.A multifunctional reconfigurable fluidic unit can be used as sensor, valve and actuator is presented. A unique configuration combines the features of the three components as a Responsive self‐oscillating actuator. The remarkable versatility of the fluidic unit is demonstrated by building different robots with the same fluidic units only by varying ...

Two-field cosmological α-attractors with Noether symmetry
Journal of High Energy Physics, 2019 We study Noether symmetries in two-field cosmological α-attractors, investigating the case when the scalar manifold is an elementary hyperbolic surface. This encompasses and generalizes the case of the Poincaré disk.

Angled decompositions of arborescent link complements
, 2006 This paper describes a way to subdivide a 3-manifold into angled blocks, namely polyhedral pieces that need not be simply connected. When the individual blocks carry dihedral angles that fit together in a consistent fashion, we prove that a manifold ...
