Singularities on flag spaces (English)
0 references
The authors' aim is to generalize the results of a previous paper [\textit{M. Božek} and \textit{K. Drechsler}, Acta Math. Univ. Comen. 58/59, 135-148 (1991; Zbl 0760.06001)]. They generalize the classical concept of flag spaces replacing the determining linear order by a partial one. The new flag spaces are algebraic varieties. The main result is as follows: A flag space has singular points if and only if its partially ordered set contains a crown.
