عنوان A note on weak phase retrievable Real Hilbert space frames نوع پژوهش مقاله ارائه شده کلیدواژهها Real Hilbert frames, Phase retrieval, Full spark, Weak phase retrieval چکیده In this manuscript, we answer to some of longstanding open problems on weak phase retrieval including: (1) A complete classification of the vectors fxig2 i=1 in R2 that do weak phase retrieval; (2) We show that frames doing weak phase retrieval in Rn must span Rn پژوهشگران فاتحاکرمی (نفر اول)، اصغررحیمی (نفر دوم)
