Universal algebra

Basis (universal algebra)

In universal algebra, a basis is a structure inside of some (universal) algebras, which are called free algebras. It generates all algebra elements from its own elements by the algebra operations in an independent manner. It also represents the endomorphisms of an algebra by certain indexings of algebra elements, which can correspond to the usual matrices when the free algebra is a vector space. (Wikipedia).

Linear Algebra - Lecture 31 - Coordinate Systems

In this video, I review the definition of basis, and discuss the notion of coordinates of a vector relative to that basis. The properties of a basis of a subspace guarantee that a vector in that subspace can be written as a linear combination of the basis vectors in only one way. The wei

The Basis of a Subspace

We've seen before the "standard basis vectors" which both span R^n and are linearly independent. However, these aren't the only sets of vectors that have these two properties. We will define such as a set as being a basis for a given subspace. Learning Objectives: 1) Define a basis. 2) I

Bases and dimension for integral linear spaces II | Abstract Algebra Math Foundations 222

We want to tackle the explicit computational question of how to find a convenient basis of an integral linear space. Given some msets, they span an integral linear space, but we would like to find a simpler basis for such a space. The algorithm which we introduce is a variant of the row re

Lie groups: Poincare-Birkhoff-Witt theorem

This lecture is part of an online graduate course on Lie groups. We state the Poincare-Birkhoff Witt theorem, which shows that the universal enveloping algebra (UEA) of a Lie algebra is the same size as a polynomial algebra. We prove it for Lie algebras of Lie groups and sketch a proof of

QED Prerequisites Geometric Algebra 8 Better notation for basis vectors

After some errata, we proceed into section 3.3 of our topic paper. This section cleans up our currently cumbersome notation of the spacetime algebra and provides a tight way to write down basis vectors. This notation also anticipates some important dualities that we will learn about soon.

Bruno Klingler - 3/4 Tame Geometry and Hodge Theory

Hodge theory, as developed by Deligne and Griffiths, is the main tool for analyzing the geometry and arithmetic of complex algebraic varieties. It is an essential fact that at heart, Hodge theory is NOT algebraic. On the other hand, according to both the Hodge conjecture and the Grothendie
