Topological Complexity and LS-Category of Certain Manifolds by Fezzeh Akhtarifar, Mohammad A. Asadi-Golmankhaneh

“…The Lusternik–Schnirelmann category and topological complexity are important invariants of topological spaces. In this paper, we calculate the Lusternik–Schnirelmann category and topological complexity of products of real projective spaces and their wedge products by using cup and zero-cup length. …”

On the Formal Integrability Problem for Planar Differential Systems by Antonio Algaba, Cristóbal García, Jaume Giné

“…We study the analytic integrability problem through the formal integrability problem and we show its connection, in some cases, with the existence of invariant analytic (sometimes algebraic) curves. From the results obtained, we consider some families of analytic differential systems in ℂ2, and imposing the formal integrability we find resonant centers obviating the computation of some necessary conditions.…”

SL$_{4}(\textbf{Z})$ is not purely matricial field by Magee, Michael, de la Salle, Mikael

“…We prove that every non-zero finite dimensional unitary representation of $\mathrm{SL}_{4}(\mathbf{Z})$ contains a non-zero $\mathrm{SL}_{2}(\mathbf{Z})$-invariant vector. As a consequence, there is no sequence of finite-dimensional representations of $\mathrm{SL}_{4}(\mathbf{Z})$ that gives rise to an embedding of its reduced $C^*$-algebra into an ultraproduct of matrix algebras.…”
