Abstract

Our first result asserts that, for linear regular operators acting from a Riesz space with the principal projection property to a Banach lattice with an order continuous norm, the $C$-compactness is equivalent to the $AM$-compactness. Next we prove that, under mild assumptions, every linear section of a $C$-compact orthogonally additive operator is $AM$-compact, and every linear section of a narrow orthogonally additive operator is narrow.

关于正交加法算子的线性截面
我们的第一个结果断言,对于从具有主投影性质的Riesz空间作用到具有阶连续范数的Banach格的线性正则算子,$C$-紧性等价于$AM$-紧度。接下来我们证明,在温和的假设下,$C$-紧正交可加算子的每个线性区间都是$AM$-紧的,并且窄正交可加运算符的每个线性区段都是窄的。
