β¦ Synopsis
We show that the number of nontrivial rational points of height at most B, which lie on the cubic surface x 1 x 2 x 3 = x 4 (x 1 + x 2 + x 3 ) 2 , has order of magnitude B(log B) 6 . This agrees with Manin's conjecture.

In this paper we find an algorithm which computes the Hilbert function of schemes Z of ''fat points'' in β«ήβ¬ 3 whose support lies on a rational normal cubic curve C. The algorithm shows that the maximality of the Hilbert function in degree Ε½ t is related to the existence of fixed curves either C its
## Abstract We prove dimension formulas for the cotangent spaces __T__ ^1^ and __T__ ^2^ for a class of rational surface singularities by calculating a correction term in the general dimension formulas. We get that it is zero if the dual graph of the rational surface singularity __X__ does not cont
