Sharp iterated-Logarithmic thresholds for quantitative measure and orbit equivalence between integer lattices

We identify the sharp iterated-logarithmic thresholds at the critical exponent for quantitative measure equivalence and orbit equivalence between integer lattices. To be more precise, let $n>m$ be two positive integers, $α$ be a positive number and $( β_j)_{j \geqslant 1}$ be a finitely supported se
