Title: Omni $n$-Lie algebras and linearization of higher analogues of Courant algebroids,
Abstract: In this paper, we introduce the notion of an omni $n$-Lie algebra and show
that they are linearization of higher analogues of standard Courant algebroids.
We also introduce the notion of a nonabelian omni $n$-Lie algebra and show that
they are linearization of higher analogues of Courant algebroids associated to
Nambu-Poisson manifolds.
