We will discuss emerging RQ optimizati on problems\, variational principles\, and reformulations to algebraic lin ear and nonlinear eigenvalue problems. We will show how to exploit underly ing properties of these eigenvalue problems for designing fast solvers\, a nd illustrate the efficacy of these solvers in applications.\n\n \n\nFor Z oom meeting information please contact tim.hoheisel [at] mcgill.ca\n DTSTART:20210204T210000Z DTEND:20210204T220000Z SUMMARY:Zhaojun Bai (UC Davis) URL:/mathstat/channels/event/zhaojun-bai-uc-davis-3279 56 END:VEVENT END:VCALENDAR
