## 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
