On smooth time functions
We are concerned with the existence of smooth time functions on connected time–oriented Lorentzian manifolds. The problem is tackled in a more general abstract setting, namely in a manifold M where is just defined a field of tangent convex cones (Cx)x∈M enjoying mild continuity properties. Under some conditions on its integral curves, we will construct a time function. Our approach is based on ...
متن کاملSmooth functions on c0
The space c0 lies at the heart of many constructions of higher order smooth functions on Banach spaces. To name a few, recall Torunczyk’s proof of the existence of C-smooth partitions of unity on WCG spaces ([12]) or Haydon’s recent constructions of C-bump functions on certain C(K) spaces ([7]). The crucial property of c0 that allows for those constructions is a rich supply of C -smooth functio...
متن کاملSmooth functions on C(K)
Natural examples of spaces satisfying (i) or (ii) are c0 and the original Tsirelson space, and Bates asked whether indeed c0 / ∈ B. The question was settled in [9] (i.e. c0 / ∈ B), a paper which was conducted without any knowledge of S. Bates’ work, and which was mainly concerned with the behavior of C-smooth real functions on c0. In order to reveal the connection between these matters, let us ...
متن کاملOn Smooth Multivariate Spline Functions
In this paper the dimensions of bivariate spline spaces with simple cross-cut grid partitions are determined and expressions of their basis functions are given. Consequently, the closures of these spaces over all partitions of the same type can be determined. A somewhat more detailed study on bivariate splines with rectangular grid partitions is included. The results in this paper can be applie...
متن کاملOn Factorizations of Smooth Nonnegative Matrix-values Functions and on Smooth Functions with Values in Polyhedra
We discuss the possibility to represent smooth nonnegative matrix-valued functions as finite linear combinations of fixed matrices with positive real-valued coefficients whose square roots are Lipschitz continuous. This issue is reduced to a similar problem for smooth functions with values in a polyhedron. 1. Motivation One of the main goals of the article is to understand what kind of optimal ...
