Title: Trial states for the dilute Bose gas

Abstract: In this talk we explore the dilute Bose gas and some of its energy properties, especially the famous Lee-Huang-Yang formula. We will focus on upper bounds and the trial states used to establish them. Here the Hard-core gas plays an interesting role as the Lee-Huang-Yang formula has yet to be proven in this case. We will explore new techniques developed to attack this problem.
