A bounded linear operator is a linear transformation between normed vector spaces that maps bounded sets to bounded sets, ensuring continuity across the entire domain. This property is crucial in functional analysis as it guarantees the operator behaves predictably under limits, making it a fundamental tool in studying infinite-dimensional spaces.

A linear transformation is a function between vector spaces that preserves vector addition and scalar multiplication, mapping lines to lines or points through the origin. These transformations can be represented by matrices, making them fundamental in solving systems of linear equations and understanding geometric transformations in higher dimensions.

A normed vector space is a vector space equipped with a norm, which assigns a non-negative length or size to each vector in the space, facilitating the generalization of concepts like distance and convergence. This structure is foundational in functional analysis and provides a framework for studying the geometry of vector spaces and the behavior of linear transformations.

Functional Analysis is a branch of mathematical analysis that studies spaces of functions and their properties, often using the framework of vector spaces and linear operators. It provides the tools and techniques necessary to tackle problems in various areas of mathematics and physics, including differential equations, quantum mechanics, and signal processing.
