Differential Analysis

Definition

Differential analysis refers to a method used in mathematics and topology that investigates how functions behave under small changes in their inputs. This concept is closely tied to calculus and provides insights into the structure and properties of mathematical objects, particularly in relation to spectra, such as those encountered in the Adams spectral sequence.
