Definability and decidability problems in number theory
September 9 to September 13, 2013
American Institute of Mathematics,
San Jose, California
and Carlos Videla
This workshop will be devoted to studying definability and decidability questions in number theory, more specifically over rational numbers and
their algebraic extensions, as well as over rings of functions of natural interest.
The main topics for the workshop are:
- (Un)Definability of integers over rational numbers and number fields, Hilbert's Tenth Problem, its stronger and weaker versions (e.g. Buchi's Problem) over rational numbers,
number fields and subrings of number fields
- (Un)Decidability of theories of various rings of functions, including rational function fields over complex numbers and function fields of positive characteristic
- Definability and Decidability in infinite extensions of rational numbers
