Abstract:
My claim of a solution was premature. I will discuss the history of the problem, introduce n-dowments and the Mitchell collapse, and prove some results that could lead to a solution. If time permits, I will correct and improve a result I talked about last summer, proving that if every Hurewicz projective set of reals in sigma-compact, then there is an inaccessible in an inner model.
