修正Weyl型算子的L^2连续性的证明方法

THE REVISION OF THE PROOF METHOD OF L^2 CONTINUITY OF THE WEYL OPERATORS

对文献[1]中Wcyl型拟微分算子的L^2连续性的证明方法中的一个错误进行了修正。利用在象征中加入衰减因子的方法,得到了正确的证明。

A mistake in the proof of L^2 continuity of the pseudo-differential operators in reference [1] is revised. The right proof is obtained by the method of puting a decay factor in symbol.
