在这一章中,我们将研究从线性赋范空间X到另一个线性赋 范空间F中的映照,亦称算子.如果Y是数域,则称这种算子为泛 函.算子和泛函我们并不陌生.例如微分算子D=云就是从连续 可微函数空间C[an6]到Ca,b]E的算子,而黎曼积分(t)dt 就是连续函数空间Ca,b]上的泛函.如果说函数是数和数之间 的对应,那末算子可说是函数和函数之间的对应,不过这是更高 级的对应而巳

1 有界函数若函数(x)在定义域D上既有上界又有下界,则 称为D上的有界函数。这个定义显然等价于,对一切x∈D,恒有f(x)≤K 有界函数的几何意义

一、凸性的定义及判定: 1.凸性的定义:由直观引入.强调曲线弯曲方向与上升方向的区别定义1设函数f(x)在区间1上连续.若对
