Abstract:

A partial differential approximant (PDA) analysis of series for the tricritical point of the mean field model of Glasser, Privman, and Schulman has been developed. All features of the tricritical point are exactly reproduced by an overwhelming majority of the trial PDAs in contrast to the mixed success of the slicewise Padé approximant method. The effect of noise on the approximant convergence is also studied.
