The summer package contains a number of FORM procedures and tables for the manipulation of harmonic sums. It is used also by the harmpol package. The library can be used for many classes of finite indefinite sums. It contains also extensive tables for Euler-Zagier type sums (harmonic sums in infinity).

The package is based on the paper:

J.A.M. Vermaseren: "Harmonic Sums, Mellin transforms and Integrals", Int. J. Mod. Phys. vol. 14 (1999) 2037.

The various files are:

summer6.h : (214 Kb) The library file with the FORM code.

summer6.h.gz : (40 Kb) the gzipped version of summer6.h.

summer.tex : (95 Kb) The LaTeX sources of the paper Note that one needs the axodraw style file in order to process these sources.

summer.tex.gz : (26 Kb) The gzipped version of harmpol.tex.

summer.ps : (280 Kb) The postscript file of the paper.

summer.ps.gz : (96 Kb) The gzipped postscript file of the paper.

table7.prc.gz : (102 Kb) The weight 7 tables for values in infinity. These are not included in summer6.h.

table8.prc.gz : (595 Kb) The weight 8 tables for values in infinity. These are not included in summer6.h.

table9.prc.gz : (3831 Kb) The weight 9 tables for values in infinity. These are not included in summer6.h.
