In this paper we define and study certain von Neumann algebra invariants associated to the Dirac operator acting on L 2 spinors on the universal covering space of a compact, Riemannian spin manifold. We first study a Novikov Shubin type invariant, which is a conformal invariant but which is not inde

✦ Synopsis
We give a sufficient condition for the validity of the implication lim
Banach space, and x g X. From this condition we derive the results given by other authors. Moreover, we give some properties about the operators that verifies the above implication, which are called Neumann operators.

The Neumann operator is an operator on the boundary of a smooth manifold which maps the boundary value of a harmonic function to its normal derivative. In this paper, the Neumann operator on the boundary of smooth, bounded, simply connected planar domains is studied. The asymptotics of the eigenvalu
A hyperbolic mixed initial boundary-value problem is investigated in which the Neumann condition and the Dirichlet condition are given on complementary parts of the boundary. An existence and uniqueness result in Sobolev spaces with additional differentiation in the tangential directions to the inte
This article gives a new approach to aggregating assuming that there is an indistinguishability operator or similarity defined on the universe of discourse. The very simple idea is that when we want to aggregate two values a and b we are looking for a value l that is as similar to a as to b or, in a
We show that the existence of a certain family of plurisubharmonic functions on a bounded domain in C n implies that the % @ @-Neumann operator associated to the domain is compact. Our condition generalizes previous work of Catlin on compactness of the % @ @-Neumann operator.
