He was thrice a contributor to the "Séminaire Bourbaki", in 1997, 1999, and 2005. In 2010, Professor Burq was an invited speaker at the International Congress of Mathematicians at Hyderabad.
Title：Propagation of smallness, spectral estimates and heat equations
Abstract:
In this talk I will present some ideas allowing to establish a correspondence betweenquantitativepropagation of smallness estimates (by A. Logunov and E. Mallinikova) for harmonic functions, estimates for the Laplace spectral projector, and control properties for heat equations. This is based on joint works with I. Moyano.
