In this note we obtain a new a priori estimate for the very weak solutions of p-Laplacian type equations with VMO coefficients when p is close to 2, and then pr
,THE PERIODIC INITIAL VALUE PROBLEM AND INITIAL VALUE PROBLEM FOR THE MODIFIED BOUSSINESQ APPROXIMAT
The Boussinesq approximation, where the viscosity depends polynomially on the shear rate,finds more and more frequent use in geological practice. In this paper,
邢台市是河北省粮食主产区之一,常年种植小麦366667公顷左右。麦田杂草是危害小麦生产、影响小麦产品质量的一个重要因素,每年因麦田草害造成的小麦产量损失约占小麦总产量的15
In this paper, the authors consider complex Ginzburg-Landau equation (CGL) in three spatial dimensions ut=ρu+(1+iγ) Δμ-(1+iμ) |u|2σu+f,where u is an unkn
京核1号是由北京市农科院作物所以杂交结合系谱法选育而成。1993年2月通过了北京市品种审定委员会审定和命名。特征特性该品种长芒、白壳、白粒,穗呈纺锤形,穗层齐,落黄好。
Global existence of small amplitude solution and nonlinear scattering result for the Cauchy problem of the generalized IMBq equation were considered in the pape
We study the Dirichlet initial-boundary value problem of the general-ized Kuramoto-Sivashinsky equation ut + uxxx + λuxx + f(u)x = 0 on the interval[0, l]. The
The author proves the uniqueness of the regularizable radial minimizers of a Ginzburg-Landau type functional in the case n - 1 < p < n,and the location of the zer
利用天府7号花生播期弹性大,迟播能高产的特点,采取麦、油收后播种、有利于解决粮油“三争”矛盾,实现粮油双高产。我局种子公司从1982年开始花生夏播高产栽培的试验示范以
The author discusses the asymptotic behavior of the radial minimizer of the p-Ginzburg-Landau functional with a weight in the case p > n ≥ 2. The location of th
