Variational Analysis
The Euclidean norm, often referred to as the 2-norm, measures the length or magnitude of a vector in Euclidean space. It provides a way to quantify how far a point is from the origin, calculated as the square root of the sum of the squares of its components. This concept is crucial in understanding normed linear spaces, where norms define distances and enable the analysis of vector properties and their behavior under various operations.
