Maximal inequality for high-dimensional cubes

Presented by: 
G Aubrun [Lyon]
Date: 
Wednesday 19th January 2011 - 14:00 to 15:00
Venue: 
INI Seminar Room 1
Abstract: 
The talk will deal with the behaviour of the best constant in the Hardy-Littlewood maximal inequality in R^n when the dimension goes to infinity. More precisely, I will sketch a simple probabilistic proof of the following result (due to Aldaz): when the maximal function is defined by averaging over all centred cubes, the Hardy-Littlewood inequality does not hold with a constant independent of the dimension.
