 Two expository notes:

 



1. Two theorems of Sarkozy (with Alex Rice)




        
In this note, we provide parallel expositions of two theorems of Sarkozy, the qualitative versions of which state that any set of natural numbers of positive upper density necessarily contains two distinct elements which differ by a perfect square, as well as two elements which differ by one less than a prime.




2. Ramsey Theory (Math 8440 course notes, Spring 2011)
