| Description: We extend the ideas presented in
[41]
to Hilbert
schemes over quotient rings defined by quasi-stable ideals. This includes
in particular Clements-Lindström rings. We study the lex-point of
these schemes and show with explicit examples that in this extension
singular lex-points are possible. |
