Abstract: The special Schubert calculus is real

The special Schubert calculus is real

Frank Sottile

Fulton asked: `How many solutions to a problem of enumerative geometry can be real?'. In this paper, we consider problems of enumerating p-planes having excess intersection with general linear subspaces and show that there is a choice of real linear subspaces osculating the rational normal curve so that all p-planes having excess intersection are real. This proves a special case of the conjecture of Shapiro and Shapiro.
