Clusterformen

Clusterformen, literally "cluster forms" in German, refers to the various morphological classes that clusters can adopt as they form and evolve. The term is used across multiple disciplines to describe the shape and internal organization of aggregates composed of smaller units, such as atoms, molecules, cells, stars, or data points.

In chemistry and materials science, clusterformen describes shapes of atomic or molecular clusters, including compact spherical clusters, fractal or dendritic clusters, and core-shell or layered structures. The formation mechanism—diffusion, attachment kinetics, and surface energy—helps determine the final morphology.

In biology, colony morphology of microorganisms can exhibit cluster-like forms, ranging from dense, rounded colonies to fingered or dendritic structures, influenced by environmental conditions and species traits.

In astronomy, star clusters show different spatial distributions and morphologies, with open clusters typically irregular and loosely bound, and globular clusters more compact and centrally concentrated.

In data analysis and network science, clusterformen points to the variety of cluster shapes detected by algorithms, from compact, roughly spherical clusters to elongated or irregular ones, affecting algorithm choice and interpretation.

Although the term is descriptive rather than tied to a single taxonomy, clusterformen emphasizes the link between formation processes and observed shapes, and it highlights the interdisciplinary nature of cluster morphology.
