Incidence Gain Graphs and Generalized Quadrangles [PDF]
We demonstrate a construction method based on a gain function that is defined on the incidence graph of an incidence geometry. Restricting to when the incidence geometry is a linear space, we show that the construction yields a generalized quadrangle provided that the gain function satisfies a certain bijective property.

Lattice Points in Orthotopes and a Huge Polynomial Tutte Invariant of Weighted Gain Graphs
, 2015 A gain graph is a graph whose edges are orientably labelled from a group. A weighted gain graph is a gain graph with vertex weights from an abelian semigroup, where the gain group is lattice ordered and acts on the weight semigroup.

Leader Election for Anonymous Asynchronous Agents in Arbitrary Networks [PDF]
, 2012 We study the problem of leader election among mobile agents operating in an arbitrary network modeled as an undirected graph. Nodes of the network are unlabeled and all agents are identical.

Accelerating Consensus by Spectral Clustering and Polynomial Filters [PDF]
, 2015 It is known that polynomial filtering can accelerate the convergence towards average consensus on an undirected network. In this paper the gain of a second-order filtering is investigated. A set of graphs is determined for which consensus can be attained

Adaptive Linear Programming Decoding of Polar Codes
, 2014 Polar codes are high density parity check codes and hence the sparse factor graph, instead of the parity check matrix, has been used to practically represent an LP polytope for LP decoding.
