Motivated by the recent proposition by Buniy, Hsu and Zee with respect to discrete space-time and finite spatial degrees of freedom of our physical world with a shortand a long-distance scales, lP and L, we reconsider the Lorentz-covariant Yang’s quantized space-time algebra (YSTA), which is intrinsically equipped with such two kinds of scale parameters… (More)
