    "abstract": "Based on the (3+1)-dimensional hydrodynamic model, the space-time evolution\nof hot and dense nuclear matter produced in non-central relativistic heavy-ion\ncollisions is discussed. The elliptic flow parameter v_2 is obtained by Fourier\nanalysis of the azimuthal distribution of pions and protons which are emitted\nfrom the freeze-out hypersurface. As a function of rapidity, the pion and\nproton elliptic flow parameters both have a peak at midrapidity.",
