Smooth scheme

In algebraic geometry, a smooth scheme of dimension n over an algebraically closed field k is a scheme that is regular and has dimension n. More generally, a scheme over a field is said to be smooth if $X\times _{k}{\overline {k}}$ is smooth for any algebraic closure ${\overline {k}}$ of k.
