On index formulas for manifolds with metric horns (1998)
Journal Article
Lesch, M., & Peyerimhoff, N. (1998). On index formulas for manifolds with metric horns. Communications in Partial Differential Equations, 23(3 & 4), 649-684

In this paper we discuss the index problem for geometric differential operators (Spin-Dirac operator, Gauss-Bonnet operator, Signature operator) on manifolds with metric horns. On singular manifolds these operators in general do not have unique close... Read More about On index formulas for manifolds with metric horns.

Journal Article
Karp, L., & Peyerimhoff, N. (1998). On the distribution of hypersurfaces equidistant from totally geodesic submanifolds in hyperbolic space. Analysis, 18, 217-225. https://doi.org/10.1524/anly.1998.18.3.217

Let H be the n-dimensional real hyperbolic space and pi: H -> M be the universal covering map of a compact Riemannian manifold M of constant curvature -1. Let P be a k-dimensional complete totally geodesic submanifold of H and P_r be the correspondin...

Non-perturbative Vevs from a local expansion. (1998)
Journal Article
Jaramillo, A., & Mansfield, P. (1998). Non-perturbative Vevs from a local expansion. Acta Physica Polonica B, 29(9), 2487-2492

We propose a method for the calculation of vacuum expectation values (VEVs) given a non-trivial, long-distance vacuum wave functional (VWF) of the kind that arises, for example, in variational calculations. The VEV is written in terms of a Schrödinge... Read More about Non-perturbative Vevs from a local expansion..
