Functional Analysis 2 | Examples for Metrics - Euclidean or Discrete Metric? [dark version]
Metric spaces aren’t just a formal definition—they come with concrete distance rules that change what “closeness” and “circles” look like. After...
Functional Analysis 3 | Open and Closed Sets [dark version]
Metric spaces generalize the familiar idea of “balls” around a point, and that single geometric object drives the definitions of open sets, boundary...
Basic Topology 1 | Introduction and Open Sets in Metric Spaces
Topology begins with a practical goal: replace “distance” with a more flexible notion of “closeness,” so tools from analysis can work in settings...
Functional Analysis 16 | Compact Sets [dark version]
Compactness in functional analysis is often summarized as “closed and bounded,” but that shortcut only works in familiar settings like 2 and 3...
Functional Analysis 21 | Isomorphisms [dark version]
Isomorphisms are the yardstick for when two mathematical spaces are “the same” in a structural sense—no information is lost, and the structure is...
Basic Topology 1 | Introduction and Open Sets in Metric Spaces [dark version]
Topology’s starting point is a shift from measuring distances to describing “closeness” through neighborhoods. The core move begins with metric...
