    A nonlinear transformation of the dispersive long wave equations in (2+1) dimensions and its applications

    Full text link
    A nonlinear transformation of the dispersive long wave equations in (2+1) dimensions is derived by using the homogeneous balance method. With the aid of the transformation given here, exact solutions of the equations are obtained

    Supercritical Nonlinear Schr\"odinger equations: Quasi-Periodic Solutions

    Full text link
    We construct time quasi-periodic solutions to the energy supercritical nonlinear Schr\"odinger equations on the torus in arbitrary dimensions. This introduces a new approach, which could have general applicability.Comment: 62 pages; Duke Math. J. (to appear

    About "On certain incomplete statistics" by Lima et al

    Full text link
    Lima et al recently claim that ({\em Chaos, Solitons & Fractals,} 2004;19:1005)the entropy for the incomplete statistics based on the normalizationipiq=1\sum_ip_i^q=1 should be S=ipi2q1lnqpiS=-\sum_ip_i^{2q-1}\ln_qp_i instead ofS=ipiqlnqpiS=-\sum_ip_i^{q}\ln_qp_i initially proposed by Wang. We indicate here that thisconclusion is a result of erroneous use of temperature definition for the incompletestatistics
