On Newman-Penrose constants of stationary space-times
Xiaoning Wu, Yu Shang
We consider the general asymptotic expression of stationary space-time. Using Killing equation, we reduce the dynamical freedom of Einstein equation to the in-going gravitational w…
Riemannian Geometry of Noncommutative Surfaces
M. Chaichian, A. Tureanu, R. B. Zhang +1
A Riemannian geometry of noncommutative n-dimensional surfaces is developed as a first step towards the construction of a consistent noncommutative gravitational theory. Historical…
Direct images of bundles under Frobenius morphisms
Xiaotao Sun
Let be a smooth projective variety of dimension over an algebraically closed field with and be the relative Frobenius morphism. For any…
Well-posedness for two-dimensional steady supersonic Euler flows past a Lipschitz wedge
Gui-Qiang Chen, Tian-Hong Li
For a supersonic Euler flow past a straight wedge whose vertex angle is less than the extreme angle, there exists a shock-front emanating from the wedge vertex, and the shock-front…
Well-posedness of the Cauchy problem for the fractional power dissipative equations
Changxing Miao, Baoquan Yuan, Bo Zhang
This paper studies the Cauchy problem for the nonlinear fractional power dissipative equation for initial data in the Lebesgue space $L^r(\mr^n)$ with $…
A Recursive Method for Determining the One-Dimensional Submodules of Laurent-Ore Modules
Ziming Li, Michael F. Singer, Min Wu +1
We present a method for determining the one-dimensional submodules of a Laurent-Ore module. The method is based on a correspondence between hyperexponential solutions of associated…
