The "Riemann-Hilbert correspondences" Winter School and Workshop
Riemann-Hilbert correspondences Winter School Workshop
2017/12/20
Recent groundbreaking developments in the theory of irregular holonomic D-modules have brought to light new relationships among D-module theory and other subjects such as Non Commutative Hodge theory,...
发展了一种基于鲁棒Riemann求解器和运动重叠网格技术计算直升机悬停旋翼流场的方法。基于惯性坐标系，悬停旋翼流场是非定常流场，控制方程为可压缩Reynolds平均Navier-Stoke方程，其对流项采用Roe近似Reimann求解器离散，使用改进的五阶加权基本无振荡格式进行高阶重构，非定常时间推进采用含牛顿型LU-SGS子迭代的全隐式双时间步方法。为实施旋转运动和便于捕捉尾迹，计算采用运动重叠...
On the Gram's Law in the Theory of Riemann Zeta Function
the Gram's Law in the Theory Riemann Zeta Function
2010/11/23
Some statements concerning the distribution of imaginary parts of zeros of the Riemann zeta\,-function are established. These assertions are connected with so\,-called `Gram's law' or `Gram's rule'. I...
Uniformization of simply connected finite type log-Riemann surfaces
simply connected finite type log-Riemann surfaces
2010/11/9
We consider simply connected log-Riemann surfaces with a finite number of ramification points. We prove that these surfaces are biholomorphic to C with uniformizations given by entire functions of th...
A generalisation of an expansion for the Riemann zeta function involving incomplete gamma functions
Zeta function Incomplete gamma functions
2010/9/17
We derive an expansion for the Riemann zeta function ζ(s) involving incomplete gamma functions with their second argument proportional to n2p, where n is the summation index and p is a positive intege...

Riemann surfaces orbifold plane tiling geometry of discrete type generalized metric
2009/3/2
In this paper, after a short introduction, we focus on some
properties of Riemann surfaces that are connected with aspects from classical
and modern crystallography. The third part of the paper cont...

A Global Solution to a Two-dimensional Riemann Problem Involving Shocks as Free Boundaries
pressure gradient equation free boundary
2007/12/11
We present a global solution to a Riemann problem for the pressure gradient system of equations. The Riemann problem has initially two shock waves and two contact discontinuities. The angle between th...
LINEAR STIELTJES EQUATION WITH GENERALIZED RIEMANN INTEGRAL AND EXISTENCE OF REGULATED SOLUTIONS
Existence of regulated solutio
2007/12/10
In this work we establish an existence theorem of regulated solutions for a class of Stieltjes equations which involve generalized fuemann kind of integrals. The general method spplied consists in con...
