Scalar curvatures in almost Hermitian geometry and some applications [PDF]
Science China Mathematics, 2019 On an almost Hermitian manifold, there are two Hermitian scalar curvatures associated with a canonical Hermitian connection. In this paper, two explicit formulas on these two scalar curvatures are obtained in terms of the Riemannian scalar curvature ...

Interior curvature estimates for hypersurfaces of prescribing scalar curvature in dimension three [PDF]
American Journal of Mathematics, 2019 :We prove a priori interior curvature estimates for hypersurfaces of prescribing scalar curvature equations in $\mathbb{R}^{3}$. The method is motivated by the integral method of Warren and Yuan.

On the Geometry of Three-dimensional Pseudo-Riemannian Homogeneous Spaces. I [PDF]
Известия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2020 The problem of establishing links between the curvature and the topological structure of a manifold is one of the important problems of geometry. In general, the purpose of the research of manifolds of various types is rather complicated.

Prescribing Morse Scalar Curvatures: Blow-Up Analysis [PDF]
International mathematics research notices, 2018 We study finite-energy blow-ups for prescribed Morse scalar curvatures in both the subcritical and the critical regime. After general considerations on Palais–Smale sequences, we determine precise blow-up rates for subcritical solutions: in particular ...

Remarks on critical metrics of the scalar curvature and volume functionals on compact manifolds with boundary [PDF]
Pacific Journal of Mathematics, 2017 We provide a general B\"ochner type formula which enables us to prove some rigidity results for $V$-static spaces. In particular, we show that an $n$-dimensional positive static triple with connected boundary and positive scalar curvature must be ...

Local energy decay for scalar fields on time dependent non-trapping backgrounds [PDF]
American Journal of Mathematics, 2017 :We consider local energy decay estimates for solutions to scalar wave equations on nontrapping asymptotically flat space-times. Our goals are two-fold. First we consider the stationary case, where we can provide a full spectral characterization of local

Stable discontinuous Galerkin FEM without penalty parameters [PDF]
, 2015 We propose a modified local discontinuous Galerkin (LDG) method for second--order elliptic problems that does not require extrinsic penalization to ensure stability.

SCALAR AND VECTOR IN COMPULATION
Открытое образование (Москва), 2016 The article deals with two fundamental data types – scalar and vector (array), without the ability of working with them one cannot solve using computer school or university tasks in mathematics, physics, chemistry and other technical training courses ...
