We introduce a definition of nonlinear n-widths and then determine the n-widths of the unit ball of the Sobolev spaceWpr inLq. We prove that in the sense of these widths the manifold of splines of… (More)

This investigation evaluated the relationship between physical fitness and performance of fire suppression tasks. The following mean +/- SD values were associated with 91 fire fighters: age 31.69 +/-… (More)

Introduction The basic integral formula for submanifolds of a Lie group Poincare's formula in homogeneous spaces Integral invariants of submanifolds of homogeneous spaces, the kinematic formula, and… (More)

We define a new class of knot energies (known as renormalization energies) and prove that a broad class of these energies are uniquely minimized by the round circle. Most of O'Hara's knot energies… (More)

Stationary processes of k-flats in \(\mathbb{E}\) d can be thought of as point processes on the Grassmannian \(\mathcal{L}\) k d of k-dimensional subspaces of \(\mathbb{E}\) d . If such a process is… (More)

A purely analytic proof is given for an inequality that has as a direct consequence the two most important affine isoperimetric inequalities of plane convex geometry: The Blaschke-Santaló inequality… (More)

We study fine differentiability properties of horizons. We show that the set of end points of generators of an n-dimensional horizon H (which is included in an (n + 1)-dimensional space–time M) has… (More)

Let (M, g) be a complete two dimensional simply connected Riemannian manifold with Gaussian curvature K < -1. If f is a compactly supported function of bounded variation on M, then f satisfies the… (More)
