Approximating reals by rationals of the form a/b^2

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/118083In this note we formulate some questions in the study of approximations of reals by rationals of the form a/b^2 arising in theory of Shr"odinger equations. We hope to attract attention of specialists to this natural subject of number theory.Number Theory11K60Approximating reals by rationals of the form a/b^2text
