A note on maximal subgroups of free idempotent generated semigroups over bands (1010.3737v3)
Published 18 Oct 2010 in math.GR
Abstract: We prove that all maximal subgroups of the free idempotent generated semigroup over a band B are free for all B belonging to a band variety V if and only if V consists either of left seminormal bands, or of right seminormal bands.
