Abstract
The -colored -complete posets correspond to certain Borel representations that are analogous to minuscule representations of semisimple Lie algebras. We classify -colored -complete posets which specifies the structure of the associated representations. We show that finite -colored -complete posets are precisely the dominant minuscule heaps of J.R. Stembridge. These heaps are reformulations and extensions of the colored -complete posets of R.A. Proctor. We also show that connected infinite -colored -complete posets are precisely order filters of the connected full heaps of R.M. Green.
