Abstract: Fourier frames are natural generalization of exponentialorthonormal basis. It has widely been used in applied analysis and studied in pure mathematics. Recently, there has been an interest in classifying measures so that its L^2 spaces admit some Fourier frames. More interestingly, some fractal singular measures will also admit Fourier frames. In this talk, we give an brief introduction on this topic and report on some of its recent advance. Tea Time: 2:30PM, R707
