Convergence of summation approximants for the Moller - Plesset series measured in growth of number of accurate decimal digits of summation results with increase of n, number of used coefficients. The summation methods are partial sums (red connected disks), Pade approximants (blue circles), quadratic approximants (green boxes), cubic, quartic, fifth and sixth degree approximants (triangles, diamonds, pentagonal and hexagonal stars respectively). |
