Hello,
Does somebody here on the list have the old macsyma newsletters lying around?
I noticed that some papers on symmetry analysis (like the overview of Hereman)
refer to macsyma newsletters 7(1990), 9 (1992) and 10 (1993), which describe the
implementation of Lie symmetries (SYM.DE) and PDELIE in macsyma.
Maybe it is only interesting from a historical perspective, but you never know...
Regards,
Nijso
