"Non-triviality of the Bounded Jump Hierarchy - Part 3"
We finish the proof that for all $B$, there is some set $A$ with $B <_{bT} A <_{bT} B^b$. We determine $\hat{h}_A$ and $\hat{h}_C$ as promised, taking into account the restrictions imposed by the construction, and prove that our choices are correct.

"Non-triviality of the Bounded Jump Hierarchy - Part 2"
We continue with the proof that for all $B$, there is some set $A$ with $B <_{bT} A <_{bT} B^b$. We start the main construction itself, check that the requirements eventually settle and are met, and we investigate the correct $\hat{h}_A$ and $\hat{h}_C$ as promised.

"Exact Groups"
There are two notions of exactness for groups, but they are not known to be equivalent outside the discrete case. I will show how we can extend this equivalence to include two larger classes of groups.
