Abstract 
The polynomial method over finite fields
The sumproduct problem over finite fields. The GuthKatz polynomial method is robust enough to extend it over finite fields. Then one can use it to derive incidence bounds there, which provide bounds on the sumproduct problem over finite fields. There are important applications of the sumproduct phenomena in computer science.
