We will focus on the fractional Laplacian on $\mathbb{R}^d$\, in which case the constan ts\, estimates of the Feynman-Kac semigroups and tresholds for contractivi ty and explosion are sharp. Namely we will discuss selected results from a rXiv:2103.06550\, joint with Bartl omiej Dyda\, Tomasz Grzywny\, Tomasz Ja kubowski\, Panki Kim\, Julia Lenczewska\, Katarzyna Pietruska-Pa\l uba or Dominika Pilarczyk.\n\nFor Zoom meeting information please contact the org anizer dmitry.jakobson [at] mcgill.ca\n DTSTART:20210430T180000Z DTEND:20210430T190000Z SUMMARY:Krzysztof Bogdan (Wroclaw) URL:/mathstat/channels/event/krzysztof-bogdan-wroclaw- 330577 END:VEVENT END:VCALENDAR
