A new notion of effective dimension (David Webb’s specialty exam) @ Keller Hall 402
Nov 30 @ 2:50 pm – 3:40 pm

David Webb will present a new notion of effective dimension, inescapable dimension, which is in a sense dual to complex packing dimension.

The latter was introduced by Freer and Kjos-Hanssen in 2013 in the context of trying to show that the reals of effective Hausdorff dimension 1 are not Medvedev above the bi-immune sets.

Webb will show that the two notions are incomparable, among other results.
