Functional analysis: Banach and Hilbert spaces

Functional analysis is a fundamental pillar of modern mathematics, primarily revolving around the concepts of normed vector spaces and linear operators. Among these spaces, Banach and Hilbert spaces hold a central position due to their structural richness and multiple applications, particularly in the resolution of differential equations, optimization, and applied sciences. Understanding the nature of … Read more

Metric spaces: distance and generalized convergence

Metrical spaces are a fundamental cornerstone in the understanding of mathematical structures where the concept of distance plays a primary role. This category of spaces allows not only to generalize the usual distance known in everyday life but also to formalize fundamental concepts such as convergence, topology, or completeness. By exploring the notion of metric … Read more

Complex analysis: holomorphic functions and residues

At the heart of modern mathematics, complex analysis stands out due to its elegance and power. This field explores functions with complex values, enhancing the understanding of differential and integral calculus in two dimensions. Holomorphic functions, which represent a particular category of differentiable complex functions, play a central role. They possess remarkable properties, notably the … Read more
