我们证明了在紧致域Ω <$Rn上积分一个(正)齐次函数f可归结为在边界Ω <$Ω上积分一个相关函数。当边界Ω由齐次函数确定时,公式简化。对指数积分和齐次函数的积分也给出了类似的结果。
We show that integrating a (positively) homogeneous function f on a compact domain Ω ⊂ Rn reduces to integrating a related function on the boundary ∂Ω. The formula simplifies when the boundary ∂Ω is determined by homogeneous functions. Similar results are also presented for integration of exponentials and logarithms of homogeneous functions.
