21 de mai. de 2024 · Within this field, Sarnak's pioneering work on "the search for almost prime values of polynomials in sparse subsets arising as the orbit of a thin group," and his efforts to produce "expanders out of some thin groups," conducted alongside Jean Bourgain, Faculty (1994–2018), and Alexander Gamburd, Member (2005–06, 2007–08, 2022 ...
26 de mai. de 2024 · Together with Prof. Jean Bourgain and Prof. Alexander Gamburd, Sarnak produced expanders from thin groups, which are highly connected sparse graphs extensively used in computer science. Their work demonstrated a crucial relationship between the minimal dimension of representations of finite linear groups and expanders.

14 de mai. de 2024 · I recently encountered two papers discussing elliptic PDEs and variational methods. The first paper claims that according to regularity theory, the solution to −Δu = ug(u2) − Δ u = u g ( u 2) in R2 R 2 belongs to W2,q loc (R2) W loc 2, q ( R 2) for any q > 2 q > 2, provided g(s) ≤ CeCs g ( s) ≤ C e C s for some positive constant C C.
Há 3 dias · Similar problems were analysed by Tao in 2001 in the context of Bourgain spaces, rather than the usual L p spaces. Such estimates are used in establishing well-posedness results for dispersive partial differential equations, following famous earlier work of Jean Bourgain, Kenig, Gustavo Ponce, and Luis Vega, among others.
