SUMMARY In this paper, we establish the global well-posedness of the Cauchy problem for the Gross-Pitaevskii equation with an rotational angular momentum term in the space R 2 .

We study the wellposedness of Cauchy problem for the fourth order nonlinear Schrödinger equations i∂ t u = −ε∆u + ∆ 2 u + P (∂ α x u) |α|2 , (∂ α x ¯ u) |α|2 , t ∈ R, x ∈ R n , where ε ∈ {−1, 0, 1}, n 2 denotes the spatial dimension and P (·) is a polynomial excluding constant and linear terms.

We study a rate-type viscoelastic system proposed by I. which is a 3_3 hyperbolic system with relaxation. As the relaxation time tends to zero, this system convergences to the well-known p-system formally. In the case where the initial data are the Riemann data such that the corresponding solutions of the p-system are centered rarefaction waves, we show… (More)

We study the initial value problem for the system of compressible adiabatic flow through porous media in the one space dimension with fixed boundary condition. Under the restriction on the oscillations in the initial data, we establish the global existence and large time behavior for the classical solutions via the combination of characteristic analysis and… (More)

We consider the Cacuhy problem for a viscous compressible rotating shallow water system with a third-order surface-tension term involved , derived recently in the modelling of motions for shallow water with free surface in a rotating sub-domain [18]. The global existence of the solution in the space of Besov type is shown for initial data close to a… (More)

In this paper, we establish the global well-posedness of the Cauchy problem for the Gross-Pitaevskii equation with an angular momentum rotational term in which the angular velocity is equal to the isotropic trapping frequency in the space R 3 .

It is conjectured that Darcy's law governs the motion of compressible porous media flow in large time. This has been justified for one-dimensional isentropic flows. In this work, we show the conjecture is true for one-dimensional adiabatic flows with generic small smooth initial data.

− Electrical unit of resistance maintained at the Center for Measurement Standards (CMS, Republic of China) is based on the second plateau of quantized Hall resistance, R H (2). Resistors are directly or indirectly compared with the R H (2). We report the procedure of the dc and ac resistance measurements at the CMS. Uncertainties associated to the… (More)
