Abstract: | Let A be a subset of a finite field
for some
prime q. If
for some > 0, then we prove the estimate
for some = ( ) > 0. This is a finite field
analogue of a result of ErS]. We then use this estimate to prove a
Szemerédi-Trotter type theorem in finite fields, and obtain a new estimate for
the Erdös distance problem in finite fields, as well as the three-dimensional
Kakeya problem in finite fields. |
