Geometry of the magnetic Steklov problem on Riemannian annuli

L Provenzano, A Savo - Communications in Contemporary …, 2024 - World Scientific
We study the geometry of the first two eigenvalues of a magnetic Steklov problem on an
annulus Σ (a compact Riemannian surface with genus zero and two boundary components) …

Two generalizations of a property of the catenary

V Coll, M Harrison - The American Mathematical Monthly, 2014 - Taylor & Francis
A well-known property of the catenary curve is that the ratio of the area under the curve to
the arc length of the curve is independent of the interval over which these quantities are …

Geometry of the Fisher–Rao metric on the space of smooth densities on a compact manifold

M Bruveris, PW Michor - Mathematische Nachrichten, 2019 - Wiley Online Library
It is known that on a closed manifold of dimension greater than one, every smooth weak
Riemannian metric on the space of smooth positive densities that is invariant under the …

A characteristic averaging property of the catenary

V Coll, J Dodd - The American Mathematical Monthly, 2016 - Taylor & Francis
It is well-known that the catenary is characterized by an extremal centroidal condition: It is
the shape of the curve whose centroid is the lowest among all curves having a prescribed …

Hanging around in non-uniform fields

F Kuczmarski, J Kuczmarski - The American Mathematical Monthly, 2015 - Taylor & Francis
We define a family of curves, the n-catenaries, parameterized by the nonzero reals. They
include the classical catenaries (n= 1), parabolas (n= 1/2), cycloids (n=− 1/2), and …

The Archimedean projection property

V Coll, J Dodd, M Harrison - Advances in Geometry, 2017 - degruyter.com
Let H be a hypersurface in ℝ n and let π be an orthogonal projection in ℝ n restricted to H.
We say that H satisfies the Archimedean projection property corresponding to π if there …

The Grazing Goat and Spherical Curiosities

M Harrison - Mathematics Magazine, 2021 - Taylor & Francis
We consider a variation of the classical Grazing Goat Problem and we explore connections
to a number of surprising properties of spheres, including the curious volume-accumulation …
