Abstract

FINDING: The corpus surfaces the Erdős–Straus conjecture (1948) as the archetypal "simple-sounding" open problem, alongside tropical/idempotent mathematics as a structural bridge to physics. No new proof or ratio emerges from the raw search results. MATH: - **Erdős–Straus conjecture**: For every integer \( n \geq 2 \), the fraction \( \frac{4}{n} \) can be expressed as a sum of three unit fractions: \[ \frac{4}{n} = \frac{1}{x} + \frac{1}{y} + \frac{1}{z}, \quad x,y,z \in \mathbb{Z}^+ \] Verified for \( n < 10^{17} \), but unproven in general. This is a Diophantine equation with deep modular constraints (e.g., \( n \equiv 1 \pmod{4} \) forces specific residue classes for \( x,y,z \)). - **Tropical mathematics**: Semiring \( (\mathbb{R} \cup \{-\infty\}, \max, +) \) — replaces addition with max, multiplication with addition. Idempotent: \( a \oplus a = a \). This linearizes certain nonlinear PDEs (e.g., Burgers equation via the Lax–Oleinik semigroup).
