Dirichlet--Neumann duality for the Basic Spectrum of Riemannian Submersions: A Supersymmetric Perspective
Vicent Gimeno i Garcia, Paulo Henryque da Costa Silva
This manuscript investigates the spectral geometry of Riemannian submersions whose fibers have a basic mean curvature. By restricting the Laplace--Beltrami operator to the space of…
Criteria for parabolicity and hyperbolicity of conductive Riemannian manifolds
Vicent Gimeno i Garcia, Ana Hurtado, Steen Markvorsen +1
Motivated by the physics of anisotropic conductive materials we consider a linear elliptic operator of divergence type on a Riemannian manifold . The…
Evolution of the Torsional Rigidity under Geometric Flows
Vicent Gimeno i Garcia, Fernán González-Ibáñez
This paper explores the behavior of the torsional rigidity of a precompact domain as the ambient manifold evolves under a geometric flow. Specifically, we derive bounds on torsiona…
Lie algebraic invariants in quantum linear optics
Pablo V. Parellada, Vicent Gimeno i Garcia, Julio José Moyano-Fernández +1
Quantum linear optics without post-selection is not powerful enough to produce any quantum state from a given input state. This limits its utility since some applications require e…
Fat equator effect and Minimality in immersions and submersions of the Sphere
Vicent Gimeno i Garcia, Vicente Palmer
Inspired by the equatorial concentration of measure phenomenon in the sphere, a result which is deduced from the general, (and intrinsic), concentration of measure in $\mathbb{S}^n…
Parabolicity of invariant Surfaces
Andrea Del Prete, Vicent Gimeno i Garcia
We present a clear and practical way to characterize the parabolicity of a complete immersed surface that is invariant with respect to a Killing vector field of the ambient space.
