HELP FOR: tubular/globalvars

SYNOPSIS:

• The tubular program package uses a variety of internal global variables in order to prepare the proper environment for calculation (this depending mainly on the current weight sequence entered by the user).

• Most internal global variables used by the tubular program package are string-variables of type `name$`. This has been done in order to avoid interference with any variable names created during a maple session.

• Most of these variables are only considered for internal purposes and therefore bear no relevance for the user.

• The following predefined variables might be of interest also for passive usage, but should under no circumstances be directly changed by the user:
  `t$` - the number of weights entered
  `p$` - the current weight sequence (always sorted) as a Maple list
  `pp$` - the least common multiple of all weights
  `N$` - the Z-rank of the Grothendieck group corresponding to coh X
  `omega$` - the dualizing element of the grading group Lp, of type Lp (a type defined within this program package; cf. tubular/Lp)
  `delta_omega$` - the degree of the dualizing element
