Abstract. Let
,
,
, denote the Veronese embedding.
Fix
and let
be the union of
lines of
passing through
and with
, where
denote the linear span (
is an angle or a coordinate frame). Set
. In this note we study the stratification
by
-rank of
. We give a sharp upper bound for this rank, prove a concision result
(in a precise quantitative way) and study some cases with high rank.
