Abstract

We present a package of VAX FORTRAN programs that analyze the information coming from two sets of FORTRAN routines. The first set of routines perform strong coupling series expansions in pure SU(2) lattice gauge theory mixed actions. The most general mixed action we are able to analyze is a mixing of the spin 1 2, 1, 3 2 and 2 representations. This set is a symbiosis between the use of algebraic outputs from REDUCE and its execution using the VAX FORTRAN language. The second set of FORTRAN routines perform the Padé approximants analysis of the series. Making a systematic study of the Padé table will give the mean value of the significant real (and complex) poles put together with its standard deviation. The programs perform the series analysis and graphical representation of the results for all the cases. © 1990.
