$\mathcal{R}$ We Living in the Matrix?
Roy Araiza and Rolando de Santiago
Connes’ embedding problem asks if every type II$_1$ factor acting on a separable Hilbert space is embeddable into an ultrapower of the hyperfinite II$_1$ factor via a nonprinciple ultrafilter. Roy Araiza and Rolando de Santiago unravel the meaning behind Connes’ embedding problem and highlight its significance.

Martin’s Conjecture: A Classification of the Naturally Occurring Turing Degrees
Antonio Montalbán
This article is about naturally occurring objects in computability theory, the area inside mathematical logic that studies the complexity of infinite countable objects. Martin’s conjecture is currently one of the main open questions in computability theory and is of great foundational importance.
Topological Invariants from Higher Categories
Nick Gurski, Niles Johnson and Angélica M. Osorno
While invariants of geometric or topological objects can be of any sort, most modern invariants are algebraic in nature. The goal of this article is to survey some of the ways in which categorical algebra can be utilized to measure topological phenomena.
