This talk can be seen as a continuation of the recent talk by Sabine B¨ogli (Durham) in the same seminar series\, whe re a counterexample to the Laptev-Safronov conjecture was presented. I wil l explain how techniques from harmonic analysis\, particularly those relat ed to Fourier restriction theory\, can be used to prove upper and lower bo unds. Then I will present new results that show that in some cases one can go beyond the threshold of the counterexample.\n\n \n\nVisit the Web site : https://archimede.mat.ulaval.ca/agirouard/SpectralClouds/\n DTSTART:20211206T170000Z DTEND:20211206T180000Z SUMMARY:Jean-Claude Cuenin (Loughborough University) URL:/mathstat/channels/event/jean-claude-cuenin-loughb orough-university-335382 END:VEVENT END:VCALENDAR
