New jump operators on equivalence relations
John D. Clemens, Samuel Coskey
We introduce a new family of jump operators on Borel equivalence relations; specifically, for each countable group we introduce the -jump. We study the elementary properties…

Relative primeness and Borel partition properties for equivalence relations
John D. Clemens
We introduce a notion of relative primeness for equivalence relations, strengthening the notion of non-reducibility, and show for many standard benchmark equivalence relations that…

Computable reducibility of equivalence relations and an effective jump operator
John D. Clemens, Samuel Coskey, Gianni Krakoff
We introduce the computable FS-jump, an analog of the classical Friedman--Stanley jump in the context of equivalence relations on the natural numbers. We prove that the computable…
