  • A class of fourth-order parabolic equation with arbitrary Initial Energy
    Nonlinear Analysis: Real World Applications, 2018
    Co-Authors: Yuzhu Han
    Abstract:

    Abstract In this paper we apply the modified potential well method to the study of the long time behaviors of solutions to a class of fourth-order parabolic equation in a bounded smooth domain of R n for arbitrary n ≥ 1 . Global existence and blow up in finite time of solutions are obtained when the Initial data satisfy different conditions. To be a little more precise, we give a threshold result for the solutions to exist globally or to blow up in finite time when the Initial Energy is subcritical and critical, respectively. Moreover, the decay rate of the L 2 norm is also obtained for global solutions. Sufficient conditions for the existence of global and blow-up solutions are also provided for supercritical Initial Energy. These improve and generalize some recent results.

  • blow up of a nonlocal semilinear parabolic equation with positive Initial Energy
    Applied Mathematics Letters, 2011
    Co-Authors: Wenjie Gao, Yuzhu Han
    Abstract:

    Abstract In this short work, a semilinear parabolic equation with a homogeneous Neumann boundary condition is studied. A blow-up result for a certain solution with positive Initial Energy is established.

  • Initial Energy density of gluons produced in very high Energy nuclear collisions
    Physical Review Letters, 2000
    Co-Authors: Alex Krasnitz, Raju Venugopalan
    Abstract:

    In very-high-Energy nuclear collisions, the Initial Energy of produced gluons per unit area per unit rapidity, (dE/L{sup 2})/d{eta} , is equal to f(g{sup 2}{mu}L) (g{sup 2}{mu}){sup 3}/g{sup 2} , where {mu}{sup 2} is proportional to the gluon density per unit area of the colliding nuclei. For an SU(2) gauge theory, a nonperturbative computation of f(g{sup 2}{mu}L) shows that it varies rapidly for small g{sup 2}{mu}L but varies only by {approx}25% , from 0.208{+-}0.004 to 0.257{+-}0.005 , for a wide range 35.36 -296.98 in g{sup 2}{mu}L . This includes the range relevant for collisions at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC). Extrapolating to SU(3), we estimate dE/d{eta} for Au-Au collisions in the central region at RHIC and LHC. (c) 2000 The American Physical Society.
