On boundaries of moduli spaces of non-singular cubic surfaces with star points

[摘要] References(13)Let P19 be the parametrizing space of cubic surfaces in P3. Let M be the moduli space of non-singular cubic surfaces and \bar{M} be a suitable compactification. We study components of boundaries of the relative subspaces of non-singular cubic surfaces with star points in P19 and in \bar{M}.
