The spectra of nonnegative integer matrices via formal power series
TL;DR: In this article, a matrix A is primitive if all entries of A are nonnegative and for some n, all entries in A are strictly positive, and for any n > 0, the nonzero part of A is the spectrum of a matrix with nonnegative entries.
Strong orbit realization for minimal homeomorphisms
TL;DR: In this article, the authors generalize Dye's Theorem and the Jewett-Krieger Theorem to the non-atomic Lebesgue probability space and show that a minimal self-homeomorphism can be chosen strongly orbit equivalent to the Borel probability if and only if the periodic spectrum of S is contained in the discrete spectrum of T.

Partially Flipped Linear Algebra: A Team-Based Approach.
TL;DR: The authors describe a partially flipped introductory linear algebra course developed by three faculty members at two different universities and describe the course design and implementation in detail, including team-developed preview videos and related in-class activities.

Isaac Kornfeld,Nicholas Ormes +1 more
TL;DR: In this paper, the authors studied minimal topological realizations of families of ergodic automorphisms (e.m.p.a.'s) on nonatomic Lebesgue probability spaces.

A Homeomorphism Invariant for Substitution Tiling Spaces
TL;DR: In this paper, the authors derived a homeomorphism invariant for polygonal tiling spaces made by substitution rules, including those tilings, like the pinwheel, which contain tiles in infinitely many orientations.
