摘要：The phase retrieval problem of a frame for a Hilbert space asks to reconstruct a vector from its intensity measurements against the frame. It arises in various fields of science and engineering. In this talk, we will focus on the phase retrieval property of group frames, which is a topic having close relation with other branches of mathematics. I will first introduce various problems on the topic for finite group frames, especially those related to the phase retrievable vectors and the maximal spanning vectors. Then I will report on some recent progress regarding those problems. If time permits, I will also explain the analogy for continuous group frames.
