Abstract: We will discuss a relation between the classes of Schwartz 
functions present in Cowling-Price's and Hardy's uncertainty principle: 
they are almost-equivalent. We also discuss on an endpoint conjecture 
version of our main result, exhibiting particular classes where it 
holds, and present applications of our main theorem, making connections 
with the recent machinery of Escauriaza-Kenig-Ponce-Vega and with bounds 
on pointwise Gaussian decay of solutions to harmonic oscillators, 
settling a conjecture of Vemuri in all but a discrete set of times. 
Joint work with João Pedro Ramos (ETH) and Aleksei Kulikov (NTNU).

/This will be a hybrid seminar. All are very welcome to join either 
online or in person. Venue: Luigi Stasi seminar room, for those wishing 
to attend in person./
