利用Stroemberg-Torchinsky分解,给出了Triebel空间Fp-q(R^n,X)上算子值傅里叶乘子的一个充分条件.在n〈min(p,q)情形下,这里给出的充分条件改进了之前已知的结果.
Using the decomposition of Stromberg-Torchinsky, an operator-valued Fourier multiplier theorem on Triebel spaces on Rn is established. The result we obtained improves our previous result in the case n 〈 min(p,q).
