Uniqueness of centers of nearly spherical bodies

Jun O'Hara

An $r^{\an}$-center of a compact body $\Om$ in an dimensional Euclidean space is a point that gives an extremal value of the regularized Riesz potential, which is the (Hadamard…

Residues of manifolds

Jun O'Hara

The Riesz -energy of a manifold is the integration of the distance between two points to the power over the product space . Considered as a function of a comp…

Möbius invariant metrics on the space of knots

Jun O'Hara

We give a condition for a function to produce a Möbius invariant weighted inner product on the tangent space of the space of knots, and show that some kind of Möbius invariant knot…

Regularization of self inductance

Jun O'Hara

We introduce several methods to define the self-inductance of a single loop as the regularization of divergent integrals which we obtain by applying Neumann (or Weber) formula for…

Characterization of balls by generalized Riesz energy

Jun O'Hara

We show that balls, circles and 2-spheres can be identified by generalized Riesz energy among compact submanifolds of the Euclidean space that are either closed or with codimension…

Regularized Riesz energies of submanifolds

Jun O'Hara, Gil Solanes

Given a closed submanifold, or a compact regular domain, in euclidean space, we consider the Riesz energy defined as the double integral of some power of the distance between pairs…
