Rational Numbers in $\times b$-invariant Set
Ruofan Li (South China University of Technology)
Abstract
Let 
be an integer and 
be a finite non-empty set of primes not containing divisors of 
. For any 
-invariant, non-dense subset 
of %24&chf=bg,s,333333&chco=ffffff)
, we prove the finiteness of rational numbers in A whose denominators can only be divided by primes in . A quantitative result on the largest prime divisors of the denominators of rational numbers in is also obtained. This is joint work with Bing Li and Yufeng Wu.
