Finite End Intervals in Definable Quotients of ,,It will be shown that in a factor lattice of the lattice of c.e. sets under inclusion with respect to a special congruence relation, there exists a finite end interval which is not a Boolean algebra.

Definable Relations on the Computably Enumerable Degrees,We review recent developments in the study of definable relations on the computably enumerable (c.e.) degrees, including the following aspects:

We prove that principal numberings are complete; completeness is independent of the oracle; the degree of any incomplete numbering is meet-reducible, uniformly complete numberings exist. We completely characterize which finite arithmetical families have a universal number
