ON NODES IN TRELLISES
S.B. Rai, P. Rao · International Journal of Pure and Apllied Mathematics · 2015
In this paper, the concept of a node in a lattice introduced by J.Duda has been extended to trellises, a non-associative generalization of a lattice.It is proved that set of all nodes of a trellis forms a distributive lattice.Also we have proved that node of a trellis is standard if and only if it is not contained in a non trivial cycle.
