Eliminating spurious poles from gauge-theoretic amplitudes
This note addresses the problem of spurious poles in gauge-theoretic scattering amplitudes. New twistor coordinates for the momenta are introduced, based on the concept of dual conformal invariance. The cancellation of spurious poles for a class of NMHV amplitudes is greatly simplified in these coordinates. The poles are eliminated altogether by defining a new type of twistor integral, dual to ...
متن کاملEliminating dual spaces
Macaulay dual spaces provide a local description of an affine scheme and give rise to computational machinery that is compatible with the methods of numerical algebraic geometry. We introduce eliminating dual spaces, use them for computing dual spaces of quotient ideals, and develop an algorithm for detection of embedded points on an algebraic curve.
متن کاملEliminating Spurious Memories in a Network of Chaotic Elements
A Globally Coupled Map (GCM) model is a network of chaotic elements that are globally coupled with each other. We have previously proposed an associative memory system based on GCM, which has a better ability than the Hop eld network. This result indicates that the dynamics of our system is more e cient than that of the Hop eld network. However, even in our system, spurious memories, i.e., syst...
متن کاملDescriptor Approach for Eliminating Spurious Eigenvalues in Hydrodynamic Equations
We describe a general framework for avoiding spurious eigenvalues — unphysical unstable eigenvalues that often occur in hydrodynamic stability problems. In two example problems, we show that when system stability is analyzed numerically using descriptor notation, spurious eigenvalues are eliminated. Descriptor notation is a generalized eigenvalue formulation for differential-algebraic equations...
متن کاملEliminating spurious lipid sidebands in 1H MRS of breast lesions.
Detecting metabolites in breast lesions by in vivo (1)H MR spectroscopy can be difficult due to the abundance of mobile lipids in the breast which can produce spurious sidebands that interfere with the metabolite signals. Two-dimensional J-resolved spectroscopy has been demonstrated in the brain as a means to eliminate these artifacts from a large water signal; coherent sidebands are resolved a...
