Further Properties of Reproducing Graphs
Many real world networks grow because their elements get replicated. Previously Southwell and Cannings introduced a class of models within which networks change because the vertices within them reproduce. This happens deterministically so each vertex simultaneously produces an offspring every update. These offspring could represent individuals, companies, proteins or websites. The connections g...
متن کاملFurther Results on Betweenness Centrality of Graphs
Betweenness centrality is a distance-based invariant of graphs. In this paper, we use lexicographic product to compute betweenness centrality of some important classes of graphs. Finally, we pose some open problems related to this topic.
متن کاملRefinement for Signal Flow Graphs
The symmetric monoidal theory of Interacting Hopf Algebras provides a sound and complete axiomatisation for linear relations over a given field. As is the case for ordinary relations, linear relations have a natural order that coincides with inclusion. In this paper, we give a presentation for this ordering by extending the theory of Interacting Hopf Algebras with a single additional inequation...
متن کاملA Categorical Semantics of Signal Flow Graphs
We introduce IH, a sound and complete graphical theory of vector subspaces over the field of polynomial fractions, with relational composition. The theory is constructed in modular fashion, using Lack’s approach to composing PROPs with distributive laws. We then view string diagrams of IH as generalised stream circuits by using a formal Laurent series semantics. We characterize the subtheory wh...
متن کامل(Co)Algebraic Characterizations of Signal Flow Graphs
One of the first publications of Prakash Panangaden is about compositional semantics of digital networks, back in 1984. Digital networks transform streams of input signals to streams of output signals. If the output streams of the components of the network are functions of their input streams, then the behavior of the entire network can be nicely characterized by a recursive stream function. In...
