Álgebra de Banach

Banach algebra is a mathematical structure that combines concepts from algebra and analysis. It’s a set equipped with an operation like multiplication, where you can add and multiply elements, and these operations follow specific rules. Additionally, there's a way to measure the “size” of elements (called a norm), and the algebra is complete, meaning all limit processes converge within it. This framework is fundamental for studying functions, operators, and their properties in advanced mathematics, providing a rigorous foundation for analysis and applications in physics, engineering, and beyond.
