Internally 4-connected binary matroids with cyclically sequential orderings
We characterize all internally 4-connected binary matroids M with the property that the ground set of M can be ordered (e0, . . . , en-1) in such a way that {ei, . . . , ei+t} is 4...

Algebraic connectivity for vertex-deleted subgraphs, and a notion of vertex centrality
Let G be a connected graph, suppose that v is a vertex of G, and denote the subgraph formed from G by deleting vertex v by G \ v. Denote the algebraic connectivities of G and G \ ...

Graph classes with given 3-connected components: asymptotic counting and critical phenomena
Fix a family T of 3-connected graphs, and let G be the class of graphs whose 3connected components are the graphs in T . We present a general framework for analyzing such graph cl...

Maintaining connectivity among multiple agents in cyclic pursuit: A geometric approach
This paper studies the connectivity maintenance problem in linear and nonlinear cyclic pursuit, when different control gains are assigned to each agent. Feasibility/infeasibility c...
