Mathematics

* Connectivity (graph theory), a property of a graph. * The property of being a connected space in topology. * Homotopical connectivity, a property related to the dimensions of holes in a topological space, and to its homotopy groups. *

Homological connectivity In algebraic topology, homological connectivity is a property describing a topological space based on its homology groups. Definitions Background ''X'' is ''homologically-connected'' if its 0-th homology group equals Z, i.e. H_0(X)\cong \math ...

Functional connectivity Resting state fMRI (rs-fMRI or R-fMRI) is a method of functional magnetic resonance imaging (fMRI) that is used in brain mapping to evaluate regional interactions that occur in a resting or task-negative state, when an explicit task is not being ...

Dynamic functional connectivity Dynamic functional connectivity (DFC) refers to the observed phenomenon that functional connectivity changes over a short time. Dynamic functional connectivity is a recent expansion on traditional functional connectivity analysis which typically ass ...
