Oscillation

Definition

Oscillation refers to the repetitive variation, often in time, of some measure about a central value or between two or more different states. In the context of multifractal analysis, oscillation can be understood as the fluctuations in the distribution of measures across scales, which are crucial for understanding complex structures and their properties.
