Title
Tameness and transexponentialism
Abstract
Three and a half decades after first being posed, the question is still open as to whether there exist o-minimal expansions of the real field that are not exponentially bounded. This is particularly striking as there have always been some seemingly obvious candidates for examples. I will discuss this issue and some other related matters, in particular, whether there exists an o-minimal expansion of the ordered additive group of rational numbers that defines a unary function from a bounded set onto an unbounded set.
