Existence of 3-Dimensional Tori for 1D Complex Ginzburg–Landau Equation Via a Degenerate KAM Theorem
In this paper, we consider complex Ginzburg–Landau equation in one space dimension and rigorously show the existence of 3-dimensional tori. The proof is based on degenerate infinite-dimensional KAM theory and normal form technique. 相似文献

The direction and magnitude of asymmetric induction in the [2+2] cycloaddition of chlorosulfonyl isocyanate to 3-O-allenyl-α-d-xylofuranoses was investigated. It is shown that gem terminal dimethylallenes react more readily than methyl free congeners. The configuration of adducts was established by X-ray and CD-spectroscopy of alkylidene cephams. A stereochemical model of the transition state for the [2+2] cycloaddition of chlorosulfonyl isocyanate and allenyl ethers is proposed, based on the lowest energy conformation of the cumulene. 相似文献

In this paper, based on some known dynamic inequalities, we investigate certain new dynamic inequalities on time scales, which provide explicit bounds on unknown functions. Our results unify and extend some continuous inequalities and their corresponding discrete analogues. 相似文献
