The character and the wave front set correspondence in the stable range

We relate the distribution characters and the wave front sets of unitary representation for real reductive dual pairs of type I in the stable range.     

The behavior of differential forms under purely inseparable extensions

Let F be a field of characteristic 2. In this paper we give a complete computation of the kernel of the homomorphism $H_2^{m+1}(F)?H_2^{m+1}(L)$ induced by scalar extension, where $L/F$ is a purely inseparable extension (of any degree), $H_2^{m+1}(F)$ is the cokernel of the Artin–Schreier operator $?:{\mathrm{\Omega }}_F^m?{\mathrm{\Omega }}_F^m/\mathrm{d}{\mathrm{\Omega }}_F^{m?1}$ given by: $x\frac{\mathrm{d}{x}_1}{x_1}\wedge ?\wedge \frac{\mathrm{d}{x}_m}{x_m}?(x^2?x)\frac{\mathrm{d}{x}_1}{x_1}\wedge ?\wedge \frac{\mathrm{d}{x}_m}{x_m}+\mathrm{d}{\mathrm{\Omega }}_F^{m?1}$, where ${\mathrm{\Omega }}_F^m$ is the space of absolute m-differential forms over F and d is the differential operator. Other related results are included.     

Perturbative manifolds and the Noether generators of nth-order Poisson equations

A manifold that contains small perturbations will induce a perturbed partial differential equation. The partial differential equation that we select is the Poisson equation – in order to explore the interplay between the geometry of the manifold and the perturbations. Specifically, we show how the problem of symmetry determination, for higher-order perturbations, can be elegantly expressed via geometric conditions.     

Two-dimensional vortex sheets for the nonisentropic Euler equations: Nonlinear stability

We show the short-time existence and nonlinear stability of vortex sheets for the nonisentropic compressible Euler equations in two spatial dimensions, based on the weakly linear stability result of Morando and Trebeschi (2008) [20]. The missing normal derivatives are compensated through the equations of the linearized vorticity and entropy when deriving higher-order energy estimates. The proof of the resolution for this nonlinear problem follows from certain a priori tame estimates on the effective linear problem in the usual Sobolev spaces and a suitable Nash–Moser iteration scheme.     

高校校园文化景观设计创意和表达

高校校园的文化景观不仅对其师生有潜移默化的教育作用,更会传达给师生归属感和认同感.以上海应用技术学院奉贤校区的"思贤庭"为例,在设计中结合地理位置、学科特色、功能定位、校园文化特色等,从场地原有的精神特性、历史文脉出发,演绎推导出校园文化景观的语境、符号等要素,形成了较有典型意义的校园文化景观表达模式.指出,文化景观创意的表达无需说教,可用"只言片语"的形式含蓄表达,重要的是营造出既符合功能需求又具有灵性的校园户外空间.     

定逆序数的n元数码置换个数的一种方法

一个确定的n元数码的排列,其道序数是不难求得的;反之,“已知逆序数,求有多少个n元置换”的问题要复杂得多。从最小数码的位置着手,充分利用逆序数是定数,给出一种解决此问题的新方法——最小数码定位法。此法通俗易懂,由此得到了逆序数为k(k=1,2,3……c_n~2)的n元数码的置换个数的一个递推公式:q_k(n)=1+q_1(n-l)+q_2(n-1)+q_3(n-1)+…+q_k(n-1)。
