Remarks on Finitely Presented Bands
Research Report 97-12
Date: 17 April 1997
For each variety of bands V and for positive integers m and k,
we give a formula for the largest integer such that for every band B in V generated
by m generators and k relations, there is a subset of the generators of that size
which generates a (relatively) free sub-band of B as a basis. We also determine the
semilattice structure of a finitely presented band and the complete structure
of a finitely presented normal band.
