Supersolvable posets and fiber-type abelian arrangements

open access: yesSelecta Mathematica
AbstractWe present a combinatorial analysis of fiber bundles of generalized configuration spaces on connected abelian Lie groups. These bundles are akin to those of Fadell–Neuwirth for configuration spaces, and their existence is detected by a combinatorial property of an associated finite partially ordered set.

The Orlik-Solomon algebra and the supersolvable class of arrangements

open access: yesInternational Journal of Algebra, 2014
According to the powerful geometric properties of the hypersolvable order on the hyperplanes of a supersolvable arrangement, we introduced a sufficient condition on the Orlik-Solomon algebra for any central arrangement to have supersolvable analogue and we showed this condition as a necessary condition (not sufficient) on the Orlik-Solomon algebra for ...

Nilpotent by Supersolvable M-Groups

open access: yes, 1985
A character of a finite group G is monomial if it is induced from a linear (degree one) character of a subgroup of G. A group G is an M-group if all its complex irreducible characters (the set Irr(G)) are monomial.In [1], Dade gave an example of an M ...

Combinatorial generation via permutation languages. VII. Supersolvable hyperplane arrangements

open access: yesEuropean Journal of Combinatorics
For an arrangement $\mathcal{H}$ of hyperplanes in $\mathbb{R}^n$ through the origin, a region is a connected subset of $\mathbb{R}^n\setminus\mathcal{H}$. The graph of regions $G(\mathcal{H})$ has a vertex for every region, and an edge between any two vertices whose corresponding regions are separated by a single hyperplane from $\mathcal{H}$.

Optimal arrangement of data in a tree directory [PDF]

open access: yes, 2001
We define the decision problem {\textsc {data arrangement}}, which involves arranging the vertices of a graph $G$ at the leaves of a $d$-ary tree so that a weighted sum of the distances between pairs of vertices measured with respect to the tree ...

Hamiltonian Cycles in Simplicial and Supersolvable Hyperplane Arrangements

open access: yes
Motivated by the Gray code interpretation of Hamiltonian cycles in Cayley graphs, we investigate the existence of Hamiltonian cycles in tope graphs of hyperplane arrangements, with a focus on simplicial, reflection, and supersolvable arrangements. We confirm Hamiltonicity for all 3-dimensional simplicial arrangements listed in the Grünbaum--Cuntz ...

A Generalization of Semimodular Supersolvable Lattices

open access: yes, 1999
Stanley [18] introduced the notion of a supersolvable lattice, L, in part to combinatorially explain the factorization of its characteristic polynomial over the integers when L is also semimodular.

A survey of the number of supersolvable subgroups of finite groups

open access: yes, 2022
In this paper we survey a new criteria for solvability of finite groups in terms of number of supersolvable (also known as polycyclic) and non-supersolvable subgroups.

Supersolvable saturated matroids and chordal graphs

open access: yes, 2023
A matroid is supersolvable if it has a maximal chain of flats each of which is modular. A matroid is saturated if every round flat is modular. In this article we present supersolvable saturated matroids as analogues to chordal graphs, and we show that ...
