报告摘要:Let m be a Borel probability measure with compact support on n-dimensional Euclidean space. We call m a spectral measure if there exists an orthonormal basis of exponential functions for its L2 space. It has been observed that the spectrality of Cantor-Moran measures is determined by equi-positivity. In this talk, I will introduce the equivalent condition of equi-positivity(joint work with Prof. Liu Jin-Song et al.).As application, we show that all singular continuous Cantor-Moran measures are spectral.
