Abstract
Fine structural inner models come in two main forms: pure extender mice L[E], and extender/strategy mice L[E,Σ], where Σ codes a partial iteration strategy for the structure. We will discuss recent results analysing HODs and mantles associated to certain pure extender mice, in terms of strategy mice. This is analogous to the analysis of HODs of determinacy models. We thereby derive the existence of iterable strategy mice with Woodin cardinals from the existence of iterable pure extender mice with interleaved Woodin and strong cardinals, and establish that the extender mice in question compute a significant fragment of their own iteration strategy. The work is partly joint with G. Sargsyan and R. Schindler.Keywords: Set theory; inner model theory; large cardinal; fine structure; self-iterability; set theoretic geology; ordinal definability
