多维积分的变量变换

Change of Variable for Multi-dimensional Integral

Isidore Fleischer

摘要:

在变换可微的唯一假设下证明了变量变换定理。具体来说,它是根据这一假设,变换积分等于给定的一个在每个可测量的子集上的变换是单射的;这可数许多这些子集涵盖域的可逆性;和它的补充-域的不可逆性-是可测量的,所以可以中断和单独处理。

英文摘要:

The change of variable theorem is proved under the sole hypothesis of differentiability of the transformation. Specifically, it is shown under this hypothesis that the transformed integral equals the given one over every measurable subset on which the transformation is injective; that countably many of these subsets cover the domain of invertibility; and that its complement -- the domain of non-invertibility -- is measurable and so may be broken off and handled separately.
