It is a measur e-valued Markov process. In this talk we consider the random density in th e absolutely continuous regime. After introducing this process and some cl assical results\, I will discuss some newly proven path properties of the density. These include (i) strict positivity of the density at a fixed tim e (for certain parameters) and (ii) a classification of the measures which the density charges almost surely when conditioned on survival. The duali ty between the superprocess and a fractional parabolic PDE is central to o ur method\, and I will discuss how the probabilistic statements above corr espond to new results about singular solutions to the PDE.\n\nLink: https: //mcgill.zoom.us/j/97093259428?pwd=d25yR0J6WGViSzFZOE5rT01YZnBJQT09\n\nMee ting ID: 970 9325 9428\n\nPasscode: problab\n DTSTART:20200923T150000Z DTEND:20200923T160000Z SUMMARY:Thomas Hughes (9IÖÆ×÷³§Ãâ·Ñ) URL:/mathstat/channels/event/thomas-hughes-mcgill-3246 32 END:VEVENT END:VCALENDAR
