We study an element of the ring of algebraic integers having the special form $1-z\lambda$. We obtain a formula for calculating its logarithmic functions. Thus, we verify the conjecture that logarithmic functions of the element $1-z\lambda$ are polynomials in $z$ such that $z$ appears only in powers that are divisors of the number of the logarithmic function.
Keywords: logarithmic function, algebraic integer of the form $1-z\lambda$, ring of algebraic integers, algebraic extension of a field
Mots-clés : $p$-adic logarithm.
