Regular embedding of codimension
WebLet $M^n$, $n\geq 3$, be a closed orientable $n$-manifold and $\mathbb{G}(M^n)$ the set of A-diffeomorp\-hisms $f: M^n\to M^n$ whose non-wandering set satisfies the ...

These defects are typically understood by their behaviour under va…
Regular embedding of codimension

A regular embedding of codimension one is precisely an effective Cartier divisor. Examples and usage. For example, if X and Y are smooth over a scheme S and if i is an S-morphism, then i is a regular embedding. In particular, every section of a smooth morphism is a regular embedding.

The curve is described in local coor-dinates by x i α = x i α (t).
