# Notation

Notation of ManifoldDiffEq.jl mostly follows the notation of Manifolds.jl. There are, however, a few changes to more closely match the notation of the DiffEq ecosystem. Namely:

`u`

is often used to denote points on a manifold.- Tangent vectors are usually denoted by $X$, $Y$ but some places may use the symbol $k$.
- Parameters of the solved function are denoted either by $p$ or
`params`

, depending on the context.
