A modified atmospheric non-hydrostatic model on low aspect ratio grids: part II
Tellus: Series A, Dynamic Meteorology and Oceanography, 2013 Sun et al. (2012) proposed a modified non-hydrostatic model (MNH), in which the left-hand side of the continuity equation is multiplied by a parameter δ (4≤δ≤16 in the article) to suppress high-frequency acoustic waves.

On the condition numbers of a multiple generalized eigenvalue
, 2010 For standard eigenvalue problems, a closed-form expression for the condition numbers of a multiple eigenvalue is known. In particular, they are uniformly 1 in the Hermitian case, and generally take different values in the non-Hermitian case.

On $\alpha$-spectral theory of a directed k-uniform hypergraph [PDF]
Computer Science Journal of Moldova, 2020 In this paper, we study a k-uniform directed hypergraph in general form and introduce its adjacency tensor, Laplacian tensor and signless Laplacian tensor. For the $k$-uniform directed hypergraph $\mathcal{H}$ and $0\leq \alpha

Electronic Journal of Differential Equations, 2017 For the n-th eigenvalue of a Sturm-Liouville eigenvalue problem with separated boundary conditions, we express the infimum of the $L^1[0,1]$ norm of potentials, in terms of a parameter $\lambda$ and the boundary conditions. Also we indicate where the

Mathematical model for the basilar membrane as a two dimensional plate
Electronic Journal of Differential Equations, 1999 In this paper we present two mathematical models for the basilar membrane. In the first model the membrane is represented as an annular region. In the second model the basilar membrane is treated as a rectangular region.

Fundamental tone of minimal hypersurfaces with finite index in hyperbolic space
Journal of Inequalities and Applications, 2016 Let M be a complete minimal hypersurface in hyperbolic space H n + 1 ( − 1 ) $\mathbb {H}^{n+1}(-1)$ with constant sectional curvature −1. We prove that if M has a finite index and finite L 2 $L^{2}$ norm of the second fundamental form, then the ...
