For functions \(f\in L^1\left( \mathbb {R}^2,\mathcal {H}\right) \) with the quaternion Fourier transform (QFT) \(\widehat{f}\) we give necessary and sufficient conditions in terms of \(\widehat{f}\) to ensure that f belongs either to one of the generalized Lipschitz classes \(H_{\alpha _1,\alpha _2}^m\) and \(h_{\alpha _1,\alpha _2}^m\) for \(0<\alpha _1,\alpha _2<m\).

四元数傅立叶变换和广义Lipschitz类
对于函数\(F \在L ^ 1 \左(\ mathbb {R} ^ 2,\ mathcal {H} \右)\)与四元数傅里叶变换(QFT)\(\ widehat {F} \)我们得到关于\(\ widehat {f} \)的必要和充分条件,以确保f属于广义Lipschitz类\(H _ {\ alpha _1,\ alpha _2} ^ m \)和\(h_ { \阿尔法_1,\阿尔法_2} ^ M \)为\(0 <\阿尔法_1,\阿尔法_2 <米\) 。
