For two subsets W and V of a normed space X. The relative Kolmogorov n-width of W relative to V in X is defined by Kn(W, V )X := inf Ln sup f W inf gV Ln f - g X, where the infimu...
We present the results of gravitational direct N-body simulations using the commercial graphics processing units (GPU) NVIDIA Quadro FX1400 and GeForce 8800GTX, and compare the re...
