High temperature series expansions of the spin-spin correlation function forthe XY (or plane rotator) model on the triangular lattice are extended by twoterms up to order beta^{14}. Tables of the expansion coefficients are reportedfor the correlation function spherical moments of order l=0 and 2. Our analysisof the series supports the Kosterlitz-Thouless predictions on the structure ofthe critical singularities and leads to fairly accurate estimates of thecritical parameters.Comment: 12 pages, LateX, figures reported only in the printed versio
