More on strongly jump-traceable reals
by
Noam Greenberg
Victoria University of Wellington

The world of low2 c.e. degrees has been getting richer recently, and the class of strongly jump-traceable reals has emerged as an interesting sub-ideal of the ideal of the K-trivial degrees. I will discuss recent results connected to the search for intermediate ideals and for new characterisations of strong jump-traceability. Also on the agenda is the location of the K-trivials in the hierarchy of jump-traceable degrees.
