inverse function theorem
解釋
反函數定理-
The global inverse function theorem is applied for the existence and uniqueness of periodical solutions to the semilinear boundary value problems. some results are improved
摘要本文運用整體反函數理論證明了一類半線性方程邊值問題周期解的存在唯一性,推廣和改進了已有的一些結果。 -
Secondly, using the relation between the weighted modified k - functional, the weighted modulus of smoothness, the weighted main - part modulus of smoothness. we get the pointwise direct and inverse approximation theorem with jacobi weight for s ' zdsz - kantorovich operator. thus some results on w ( x ) = 0 ( w ( x ) denotes the weight function ), ditzian - totik modulus and classic modulus are extend
其次,引入一種改變的帶權k -泛函,利用帶權光滑模和帶權主部光滑的關系及帶權光滑模與改變帶權k -泛函的等價性,關于sz sz - kantorovich運算元,討論了一階矩不為零的運算元的點態帶jacobi權逼近正定理及等價定理,推廣了已有的權為零及ditzian - totik光滑模和古典光滑模的結果。
