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.
