开尔文-台特-切塔耶夫定理中关于含保守力和陀螺力的线性系统稳定性条件指出:若保守系统不稳定,特征值无零根且不稳定度(具有正实根特征值的数目)为偶数,则陀螺力的加入可使系统转为稳定。

In this talk,we first discuss the global well-posedness of rotating shallow water system with the small smooth initial data,where the dispersion of the system w
In a fluid with a non-monotonic state equation,say van der Waals fluid,nonclassical shock waves like subsonic phase transition usually appear whose characterist
The talk is mainly concerned with some recent studies on the generalized MHD and Hall-MHD systems.First,we will give a brief review of progress on well-posednes
In this talk,we start with a general linear Hamiltoniansystem ut = J Lu in a Hilbert space X-the energy space.Weassume that(a)J ∶ X*(∩)D(J)→ X is anti-self-a
In this talk,we study the three-dimensional axisymmetric Navier-Stokes system with nonzero swirl.By establishing a new key inequality for the pair(wr,wθ),we ge
We consider vanishing viscosity limit for systems of strictly hyperbolic conservation laws in one space dimension with nonidentity viscosity matrix.
In this talk,we discuss about large time behavior of global solutions tosome dissipative PDES in nonlinear conservation laws.
This work is motivated by a paper of Bourgain,Brezis and Mironescu.In this paper,the authors give a new insight onclassical Sobolev spaces.They establish new co
It is well-known that shock will form in finite time for hyperbolic conservation laws from initial compression no matter how small and smooth the data are.Class
We propose a conservation-dissipation formalism(CDF)for coarse-grained descriptions of irreversible processes.This formalism is based on a stability criterion f
