在弹性波导槽中非线性应变波的指数吸引子
Exponential Attractor of Nonlinear Strain Waves in Elastic Wavegujdes
【摘要】 研究了在弹性波导槽中非线性应变波方程生成的非线性连续半群的性质,通过算子分解和构造渐近紧不变集,得到了在空间E1中半群 S(t)导出的紧的指数吸引子.
【Abstract】 The properties of the sem: group of monlinear strain waves in elastic waveguides is considered. By decomposing the operater and constructing the asymptotical compact in variant set, the authors obtained the compact exponential attractor.
