Hilbert Spaces 1 | Introductions and Cauchy-Schwarz Inequality
Hilbert spaces hinge on one foundational idea: an inner product that turns a vector space into a geometric setting where lengths, angles, and...
Hilbert Spaces 2 | Examples of Hilbert Spaces
Hilbert spaces are best understood as complete inner-product spaces: start with a vector space over either the real numbers or the complex numbers,...
Manifolds 33 | Riemannian Metrics
Riemannian geometry starts by turning an abstract smooth manifold into a space where distances, lengths, and angles actually make sense. The key move...
Abstract Linear Algebra 12 | Cauchy-Schwarz Inequality
Cauchy–Schwarz inequality becomes the bridge between inner products and geometry: it turns the inner product of two vectors into a quantity...
Functional Analysis 9 | Examples of Inner Products and Hilbert Spaces [dark version]
Hilbert spaces come from vector spaces equipped with an inner product that makes the induced metric complete—but having an inner product alone is not...
Abstract Linear Algebra 10 | Inner Products
General inner products are the mechanism that turn a purely algebraic vector space into a geometric one—enabling notions of length and angle even...
Hilbert Spaces 2 | Examples of Hilbert Spaces [dark version]
Hilbert spaces are built from vector spaces plus an inner product, and the key practical takeaway is that many familiar “function” and “sequence”...
Abstract Linear Algebra 10 | Inner Products [dark version]
General inner products are introduced as the mechanism that turns a purely algebraic vector space into one with geometry—so angles and lengths become...
Abstract Linear Algebra 12 | Cauchy-Schwarz Inequality [dark version]
Cauchy–Schwarz inequality is the engine behind how inner products turn algebraic vector spaces into geometric ones: it bounds the inner product of...
