WebThe answer is simple. We pick different representations of the Lorentz algebra, and then define the fields to transform under that representation! For example. Objects transforming under the trivial representation are called scalars. Objects transforming under S μ ν are called spinors. Objects transforming under J μ ν are called vectors.

WebRepresentation theory is a branch of mathematics that studies abstract algebraic structures by representing their elements as linear transformations of vector spaces, and studies modules over these abstract algebraic structures. [1] [2] In essence, a representation makes an abstract algebraic object more concrete by describing its … WebThere are so many words that you come across when you’re working on algebra problems, and these words are really code for very specific mathematical symbols.

WebThe authors then go on to study representations of quivers in detail, leading to a complete proof of Gabriel's celebrated theorem characterizing the representation type of quivers in terms of Dynkin diagrams. Requiring only introductory courses on linear algebra and groups, rings and fields, this textbook is aimed at undergraduate students. WebMar 15, 2024 · The algebra $ A $ is said to be representation-finite if there are only finitely many isomorphism classes of indecomposable representations of $ A $; it is called tame if it is not representation-finite but all families of indecomposable representations are $ 1 $-parametric, and wild if the category $ A $-mod of all finite-dimensional $ A ...
