DStrips is a simple and efficient method to dynamically manage and generate triangle strips for real-time viewdependent multiresolution meshing and rendering. Progressive view-dependent triangle mesh simplification and rendering is an important concept for interactive visualization environments. To minimize the rendering cost, triangle meshes are simplified to the maximal tolerated perceptual e...

this paper is concerned with the following elliptic system:$$ left{ begin{array}{ll} -triangle u + b(x)nabla u + v(x)u=g(x, v), -triangle v - b(x)nabla v + v(x)v=f(x, u), end{array} right. $$ for $x in {r}^{n}$, where $v $, $b$ and $w$ are 1-periodic in $x$, and $f(x,t)$, $g(x,t)$ are super-quadratic. in this paper, we give a new technique to show the boundedness of cerami sequences and establi...
