Smooth globally hyperbolic splittings and temporal functions
Geroch’s theorem about the splitting of globally hyperbolic spacetimes is a central result in global Lorentzian Geometry. Nevertheless, this result was obtained at a topological level, and the possibility to obtain a metric (or, at least, smooth) version has been controversial since its publication in 1970. In fact, this problem has remained open until a definitive proof, recently provided by t...
متن کاملSmooth distributions are globally finitely spanned
A smooth distribution on a smooth manifold M is, by definition, a map that assigns to each point x of M a linear subspace ∆(x) of the tangent space TxM , in such a way that, locally, there exist smooth sections f1, . . . , fd of ∆ such that the linear span of f1(x), . . . , fd(x) is ∆(x) for all x. We prove that a much weaker definition of “smooth distribution,” in which it is only required tha...
متن کاملA Novel 36-pulse rectifier with low kVA rate to reduce harmonic input current distortion
The increase in the number of pulses in multipulse rectifiers leads to a reduction in harmonic current distortion. But this increase in the number of pulses leads to an increase in kVA, cost, and complexity of the multi-pulse rectifiers. As a result, in industrial applications, 12-pulse rectifiers are mainly used due to their lightweight, simple transformers, and low kVA rate, and low cost. The...
متن کاملAnalog Filter Banks with Low Intermodulation Distortion
It is demonstrated that the filter-bank structure of [1] can be designed to significantly reduce the effect of intermodulation distortion. This gives it an important advantage over other structures in radio systems. The principle is explained, and supported with Volterra analysis and simulation.
متن کاملBijective spherical parametrization with low distortion
Computing a bijective spherical parametrization of a genus-0 surface with low distortion is a fundamental task in geometric modeling and processing. Current methods for spherical parametrization cannot, in general, control the worst case distortion of all triangles nor guarantee bijectivity. Given an initial bijective spherical parametrization, with high distortion, we develop a non-linear cons...
