The decomposition of a set into "cylinders" in one of the fundamental
tools of semi-algebraic geometry (as well as subanalytic geometry and
o-minimal geometry). Defined by means of intervals, these cylinders are
an essentially real-geometric construct.
In a recent paper wit Novikov we introduce a notion of "complex cells",
that form a complexification of real cylinders. It turns out that such
complex cells admit a rich hyperbolic geometry, which is not directly
visible in their real counterparts. I will sketch some of this theory,
and how it can be used to prove some new results in real geometry (for
instance a sharpening of the Yomdin-Gromov lemma).
