Symbolic powers of the ideal of$n$ general points in $P^{n-1}$

Problem L of Fr\"oberg--Lundqvist--Oneto--Shapiro asks for the difference between the Hilbert series of ordinary and symbolic powers of the ideal of general points in projective space. We solve this completely for $n$ general points of $\PP^{n-1}$. Besides a closed formula for \[ \HS(S/I^m)-\HS(S/I^{(m)}), \] we de...
