Generalized Derivations of n-BiHom-Lie algebras

We investigate generalized derivations of $n$-BiHom-Lie algebras. We introduce and study properties of derivations, $({\alpha }^s,{\beta }^r)$-derivations and generalized derivations. We also study quasiderivations of $n$-BiHom-Lie algebras. Generalized derivations of $(n+1)$-BiHom-Lie algebras induced by $n$-BiHom-Lie algebras are also considered.
