Serienschlankheit

Serienschlankheit is a term used in German-language discourse to describe a property of a series or sequence that emphasizes conciseness and efficiency. The word combines Seri e (series) and Schlankheit (slenderness or trimness), and its precise meaning varies by discipline.

In mathematics and analysis, Serienschlankheit may denote a series that exhibits rapid tail decay, allowing accurate approximations with only a few terms. A common informal formalization is the existence of a bound indicating geometric-type decay of successive terms, which yields small remainder estimates. The concept is also used to describe representations of functions where the coefficients of the basis expansion diminish quickly, enabling compact descriptions.

In data science and signal processing, Serienschlankheit can refer to the ability to represent a time series with a small number of coefficients or basis functions, leading to efficient compression, reduced storage, and faster computations.

In media studies and design, the term may describe a principle of lean construction for serialized products, such as television series or product lines, aiming for economical storytelling, minimal redundancy, and consistent pacing across episodes or items.

Criticism and limitations: Serienschlankheit is not a universally standardized term, and its definition can vary between writers and fields. Its usefulness depends on the context and the availability of appropriate models or metrics to quantify “slenderness.”
