The elementary properties of n sort of separate function which can be described maximum function or minimal function are researched 摘要主要討論一類能表示成最大值函數(shù)、最小值函數(shù)的分段函數(shù)的初等性。
In section 5 , , e are in a position to consider some properties , mainly oscillation , cycle length and periodicity , etc , for a rational difference equation involving maximum function , partly solving an open problem . several natures for lyness equation are studied in section 6 第六節(jié)中研究了tyness方程的一些性質(zhì);首先對于常系數(shù)的tyness方程,得到了其周期性的幾個(gè)充分條件,尤其是5一周期的充要條件;據(jù)此解決了一個(gè)關(guān)于差分方程周期性的公開問題;然后把這個(gè)方程推廣到一般情形,研究其振動(dòng)性、環(huán)長與周期性等。
We give the analysis of the fundamental maximum function , by twice integrating a core function and find four type smoothing approximations for it through convolution . we continue to find the smoothing approximations of general maximum function . at last we propose the parametric smoothing approximations of the original problem 先選擇適當(dāng)?shù)暮撕瘮?shù),再利用卷積理論得到可以替代最簡單的最大值函數(shù)的光滑函數(shù);再進(jìn)一步找到替代一般的最大值函數(shù)的光滑函數(shù),最后解決本文要解決的非光滑優(yōu)化問題。
