A modular characterization of supersolvable lattices (2011.11657v2)
Published 23 Nov 2020 in math.CO
Abstract: We characterize supersolvable lattices in terms of a certain modular type relation. McNamara and Thomas earlier characterized this class of lattices as those graded lattices having a maximal chain that consists of left-modular elements. Our characterization replaces the condition of gradedness with a second modularity condition on the maximal chain of left-modular elements.
