We provide complete characterisations for the compactness of weighted composition operators between two distinct $L^{p}$ -spaces, where $1\leq p\leq \infty$ . As a corollary, when the underlying measure space is nonatomic, the only compact weighted composition map between $L^{p}$ -spaces is the zero operator.

空间之间的紧凑加权组合算子
我们为两个不同的加权合成算子的紧凑性提供了完整的特征$L^{p}$ -空格,其中$1\leq p\leq \infty$ . 作为推论,当底层测量空间是非原子的时,之间唯一的紧凑加权组合图$L^{p}$ -spaces 是零运算符。
