Hi, 誠信: You made a comment on one of the blogs that Terry Tao make a mistake in his proof of a fundamental theorem on compressed sensing. I asked for links/references for that erroneous proof and perhaps corrections for it. But I have not heard back from you. Would you be so kind as to email me any pertinent information you have? Much obliged Yours Sincerely Nightrider
