In this talk, we will start by reviewing some basic ideas from the previous talk, and start developing the machinery required to prove Shelah's full result:  If lambda is an inaccessible Jonsson cardinal, then lambda must be lambda x omega Mahlo. Along the way, we will discuss Shelah's rank ideals as well as related club guessing results.   Building 502, Room 37 אוניברסיטת בר-אילן - המחלקה למתמטיקה mathoffice@math.biu.ac.il Asia/Jerusalem public

Abstract
In the previous talk, we showed that if lambda is an inaccessible Jonsson cardinal, then lambda must be Mahlo.

Along the way, we will discuss Shelah's rank ideals as well as related club guessing results.
