Standard morphisms and Pythagorean triples

João Araújo, André Carvalho

Let $m \geq 1$ , let $f : N \to Z / m Z$ be a standard morphism and let $T (m)$ be the least integer $N$ such that every such $f$ admits a primitive monochromatic Pyt…

Analysis of a multispecies cross-diffusion Keller-Segel system with volume filling

Noah Geltner, Ansgar JÃ¼ngel, Mingyue Zhang

The paper analyzes a chemotaxis-driven multispecies cross‑diffusion Keller‑Segel system with volume‑filling constraints, establishing global weak existence, weak‑strong uniqueness,…

Well-posedness and asymptotic limits for a degenerate Keller-Segel system with volume filling

Noah Geltner, Ansgar JÃ¼ngel, Mingyue Zhang

A class of parabolic-parabolic Keller-Segel systems with degenerate diffusion and volume filling is studied in a bounded domain subject to no-flux boundary conditions. The equation…

Chemotaxis guidance of random walkers modeling self-wiring of neural networks

Noah Geltner, Ansgar JÃ¼ngel

A stochastic walker model is proposed to describe the chemotactic guidance of growth cones, i.e. the tips of developing neurites. The model accounts for the influence of both attra…
