1摘要:

    Thistalk is concerned with constructing nodal radial solutions forgeneralized

quasilinearelliptic equations in R^N with critical growth which arise fromplasma physics,

fluidmechanics,as well as high-power  ultashort laser in matter.Wefind the critical

exponentsfor a generalized quasilinear elliptic equations and obtain theexistence of

sign-changingsolution with k nodes for any given integer k > 0.

2摘要:

   主要研究了可压缩N-S方程(牛流体和非牛流体)解的适定性及长时间。具体问题涉及自由界的运,粘性系数依于密度和温度以及波的定性问题等。

3摘要:

    Groundstates of two dimensional attractive Bose-Einstein condensates (BEC)can be described equivalently by an L^2-critical constraintvariational problem. We discuss some analytic properties of suchground states, including the existence, uniqueness, symmetry-breakingand refined blow-up profiles as well.
