Topic
Arithmetic progressions in sumsets of geometric progressions
Speakers
Details
If A and B are two geometric progressions, we characterize all 3-term arithmetic progressions in the sumset A+B. Somewhat surprisingly, while mostly elementary, this appears to require quite deep machinery from Diophantine Approximation.
