We revisit the Harder-Narasimhan stratification on a minuscule padic flag variety, by the theory of modifications of G-bundles on the FarguesFontaine curve. We compare the Harder-Narasimhan strata wit...
仿射Deligne-Lusztig簇首先由Rapoport引入。其几何结构蕴含了志村簇重要的算术信息。不可约分支的参数化问题是仿射Deligne-Lusztig簇研究领域的一个主要的公开问题。为了解决这一难题, 陈苗芬和朱歆文提出了一个著名猜想：不可约分支的轨道集与Weyl模的特定权空间的晶体基之间存在典则的一一对应。通过构造不可约分支上的晶体结构，我们给出了陈-朱猜想的完整证明，并得到了计算不可...

This paper considers polynomial optimization with unbounded sets. We give a homogenization formulation and propose a hierarchy of Moment-SOS relaxations to solve it. Under the assumptions that the fea...
提出一般多边形面积坐标约束条件的构造方法，即根据基多边形选取合适的形状特征参数，然后用形状特征参数表示出一组特定的点的面积坐标，由此得出多边形面积坐标的约束条件。最后就四边形、五边形情形，给出多组等价的面积坐标约束条件，利用面积坐标约束条件解决面积坐标分量相等的点的存在性问题。

理工类研究生 创新能力培养 模式建构 差异化
2018/8/14
目前我国理工类研究生创新能力培养存在着创新意识不强、培养模式固化、支撑体系不力等几大问题。这种现状亟待变革。根据我国教育现状，借鉴传统的因材施教与西方的群类教育思想，将研究生创新能力的培养模式划分为专业精深型、应用转化型、产学研一体型三大类，据此设计不同的招考方式、课程设置、科研训练、实践教育等环节，建构差异化的培养模式。三类模式异同交错、合作互助，共同推进研究生创新能力的培养。

We use Young’s raising operators to introduce and study double
eta polynomials, which are an even orthogonal analogue of Wilson’s double
theta polynomials. Our double eta polynomials give Giambelli ...

2015/12/17
We present gluing formulas for zeta regularized determinants of Dolbeault laplacians on Riemann surfaces. These are expressed in terms of determinants of associated operators on surfaces with boundary...
Classical Teichmüller theory provides links between complex analytic and dynamical quantities defined on Riemann surfaces with conformal hyperbolic metrics. More precisely, properties of the geodesic ...
