摘要: We introduce 2-microlocal Besov spaces which generalize the \({C}_{{x}_{0}}^{s,s^{\prime}}(\mathbb{R}n)\) by Bony. give a unified Fourier-analytic approach to define generalized and we present wavelet characterization for them. Wavelets provide powerful tool studying global local regularity properties of functions. Further, prove with wavelets version first connections generalizations theory.
