Erdős--Straus Conjecture: Modular Inversion in Mordell Classes

Abstract

We examine modular inversion of strict Grid certificates in a ceiling continued-fraction construction for the Erdős--Straus equation. The six Mordell classes modulo $840$ form four inversion orbits. Prime-input pattern frequencies in the pairs $121 \leftrightarrow361 $ and 289 ↔ 529 have equal asymptotic limits for every fixed cutoff.
