Let G be a compact Hausdorff group and H be a closed subgroup of G. In this paper, we show that every bounded linear operator T on is a pseudo-differential operator with the symbol σ for . We present necessary and sufficient conditions on symbols to ensure that a bounded pseudo-differential operator on is self-adjoint, normal and present explicit formula for their symbols. A necessary and sufficient condition is also given such that the bounded linear operators on posses eigenvalues and eigenfunctions.

紧群齐次空间上伪微分算子的自伴随性、正态性表征
令G为紧 Hausdorff 群,H为G的闭子群。在本文中,我们证明了每个有界线性算子T是一个伪微分算子,符号σ为. 我们提出了关于符号的充分必要条件,以确保有界伪微分算子在是它们符号的自伴随、正常和现在的显式公式。还给出了一个充分必要条件,使得有界线性算子具有特征值和特征函数。
