= De Rham invariant
{wiki=De_Rham_invariant}
The De Rham invariant, often denoted as \\( \\psi \\), is a topological invariant associated with smooth manifolds in differential geometry. It plays a role in the study of differential forms, cohomology, and the topology of manifolds. The De Rham invariant is particularly relevant in the context of differentiable manifolds.
