KPP Dynamics in Predator–Prey Models: A Survey and a Mussel–Algae Case Study

open access: yesStudies in Applied Mathematics, Volume 157, Issue 3, September 2026.
ABSTRACT We discuss traveling fronts in several coupled reaction–diffusion systems that model predator–prey interactions, as well as other systems that share similar structural features. We review some cases where the traveling fronts exist and are small perturbations of fronts in certain scalar equations of Fisher–KPP or Burgers–FKPP type.

Square Root of a Multivector of Clifford Algebras in 3D: A Game with Signs

open access: yesMathematics
An algorithm is presented to extract the square root from a multivector (MV) in real Clifford algebras Clp,q, where n=p+q≤3, in radicals. It is shown that in Cl3,0, Cl1,2, and Cl0,3 algebras, there are up to four isolated square roots in a case of the ...

Lax Pairs for BKM Hierarchy

open access: yesStudies in Applied Mathematics, Volume 157, Issue 3, September 2026.
ABSTRACT We construct Lax pairs for the recently (2023) introduced integrable PDE systems known as the BKM equations. As many known and previously studied integrable systems are special cases of the BKM systems, our construction provides Lax pairs for many integrable hierarchies, including previously studied ones such as Camassa–Holm, Dullin–Gottwald ...

h$h$‐Function, Hilbert–Kunz density function and Frobenius–Poincaré function

open access: yesJournal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract Given ideals I,J$I,J$ of a noetherian local ring (R,m)$(R, \mathfrak {m})$ such that I+J$I+J$ is m$\mathfrak {m}$‐primary and a finitely generated R$R$‐module M$M$, we associate an invariant of (M,R,I,J)$(M,R,I,J)$ called the h$h$‐function.

Transcranial direct current stimulation enhances delayed retention after 5 days of lower‐limb motor skill learning

open access: yesThe Journal of Physiology, Volume 604, Issue 17, Page 7375-7399, 1 September 2026.
Abstract figure legend Schematic overview of the 5 day lower‐limb motor skill learning protocol combining ankle visuomotor practice with transcranial direct current stimulation (tDCS). Participants were allocated to motor skill practice with active tDCS over the leg representation of primary motor cortex (SKILL‐STIM), motor skill practice with sham ...
