    "abstract": "We investigate propagation of light pulses in photonic crystals in the\nvicinity of the zero-diffraction point. We show that Gaussian pulses due to\nnonzero width of their spectrum spread weakly in space and time during the\npropagation. We also find the family of nonspreading pulses, propagating\ninvariantly in the vicinity of the zero diffraction point of photonic crystals.",
