Multiplicative independence in the sequence of $k$-generalized Lucas numbers

Abstract: Let $(L_n^{(k)})_{n\geq 2-k}$ be the sequence of $k$-generalized Lucas numbers for some fixed integer $k\ge 2$, whose first $k$ terms are $0,\;\ldots\;,\;0,\;2,\;1$ and each term afterward is the sum of the preceding $k$ terms. In this paper, we find all pairs of the $k$-generalized Lucas numbers that are multiplicatively dependent.
