Abstract

Typed $\lambda$-terms that use variables of any order and don't use constants of order $>1$ are studied in the paper. An algorithm of translation of typed $\lambda$-terms to untyped $\lambda$-terms is presented. According to that algorithm, each typed term $t$ is mapped to an untyped term $t'$. We study in which case typed terms $t_1$, $t_2$ such that $t_1 \to \to_{\beta\delta} t_2$ correspond to untyped terms ${t_1}',{t_2}'$ such that ${t_1}' \to\to_\beta {t_2}'.$
