Peakomplektili

Peakomplektili is a term used in theoretical network analysis to describe a subgraph pattern formed around a single dominant hub. The structure is characterized by a central node connected to several peripheral nodes that are only loosely interconnected. The arrangement often produces a noticeable peak in local centrality measures and can influence information flow within the surrounding network.

Different variants exist. In the simplest form, the peak, or hub, connects to all peripherals with few or no ties among the peripherals themselves. In broader versions, some peripheral-peripheral connections are allowed, forming a denser cap around the hub while keeping the hub distinct as the most central element.

Applications include studying diffusion dynamics, resilience to targeted attacks, and organizational influence structures. The hub's removal typically has large effects on connectivity and speed of spread, while peripherals play a secondary role in maintaining local clustering.

Because peakomplektili is a coined term rather than a standardized concept, formal definitions and metrics vary by context. It is often treated as a motif or role within larger networks, and detection relies on centrality criteria or motif-search techniques.

See also includes hub-and-spoke models, star graphs, and centrality motifs. The term remains informal and primarily used in theoretical discussions or exploratory analyses rather than in established literature.
