cohTable(ZZ,ZZ,Triplet) -- cohomology table

Synopsis

• Function: cohTable

• Usage:

  cohTable(lo,hi,T)

• Inputs:
  • lo, an integer, the leftmost degree of the table
  • hi, an integer, the rightmost degree of the table
  • T, an instance of the type Triplet, a homology triplet
• Outputs:
  • a Cohomology tally, a hypercohomology table
