Sum-Product and Character Sums in finite fields
Monday November 3, 2008
02:15PM - 03:00PM
Speakers:
Mei-Chu Chang
Abstract:
In this talk I will present estimates on incomplete character sums in finite
fields, with special emphasize on the non-prime case. Some of the results
are quite recent and of the same strength as Burgess celebrated theorem for
prime fields. The improvements are mainly based on arguments from arithmetic
combinatorics providing new bounds on multiplicative energy and an improved
amplification strategy.
