A type I conjecture and boundary representations of hyperbolic groups
We establish new results on the weak containment of quasi-regular and Koopman representations of a second countable locally compact group G associated with nonsingular G-spaces. We deduce that any two boundary representations of a hyperbolic locally ...
WILEY2023Multiplicative chaos of the Brownian loop soup
Antoine Pierre François Jego, Titus Lupu
We construct a measure on the thick points of a Brownian loop soup in a bounded domain D of the plane with given intensity theta>0, which is formally obtained by exponentiating the square root of its occupation field. The measure is construct ...
WILEY2023Fourier uniqueness and interpolation in Euclidean space
We prove that every Schwartz function in Euclidean space can be completely recovered given only its restrictions and the restrictions of its Fourier transform to all origin-centered spheres whose radii are square roots of integers. In particular, the only ...
EPFL2022Modified snaking in plane Couette flow with wall-normal suction
Tobias Schneider, Sajjad Azimi
A specific family of spanwise-localised invariant solutions of plane Couette flow exhibits homoclinic snaking, a process by which spatially localised invariant solutions of a nonlinear partial differential equation smoothly grow additional structure at the ...
