关于Kantorovich定理与Moore定理的等价性 总被引:1,自引:0,他引:1
Rall就Kantorovich定理与近年来新发展的关于区间迭代的Moore定理作了比较,指出前者在“敏感性”与“精确性”方面稍胜于后者,而在应用上后者所需要的计算量却少得多。本文证明这二个定理在理论上也是等价的。 相似文献

Consider the system of ordinary differential equation u”(t)+grad G(u(t))=p(t),(1)where p:R→R”is continuous and 2π periodic and G:R~π→R has continuous secondorder partial derivatives.The system can be interpreted physically as the Newto-nian equation of motion of a mechanical system subject to conservative internalforces and the periodic external forces. 相似文献
