Discussion Overview

The discussion revolves around the mathematical nature of spinor spaces, particularly whether they can be classified as complex vector spaces. Participants explore the connections between spinors and vector spaces, seeking to clarify the definitions and relationships involved.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant suggests that spinor spaces can be thought of as vector spaces over the field of complex numbers.
  • Another participant agrees, affirming that spinors indeed form a vector space over complex numbers.
  • A participant questions whether complex vector spaces and spinor spaces are equivalent or if spinor spaces are a specific case of complex vector spaces.
  • There is a request for book recommendations that connect the concepts of spinor spaces and complex vector spaces.
  • Another participant proposes examining the multiplication table and matrix structure to gain a deeper understanding of the algebra involved in spinor spaces.
  • Discussion includes the suggestion to consider complex numbers in the context of Grassmann algebras and their geometric interpretations related to rotations and scaling.

Areas of Agreement / Disagreement

Participants generally agree that spinors are related to complex vector spaces, but there is no consensus on whether they are equivalent or if one is a subset of the other. The discussion remains unresolved regarding the precise relationship between these concepts.

Contextual Notes

Participants express uncertainty about the definitions and connections between spinor spaces and complex vector spaces. There are references to specific mathematical structures and concepts that may require further exploration to fully understand the topic.

Hi, i don't find much about spinor spaces. I can think in that spaces like a vector space above the field of complex numbers (a complex vector space)?

sorry if what i saying is a non-sense, but i really want to understand better the math behind the concept of a spinor.

thanks

Thanks Simon Bridge, I am already seen before the wikipedia article but is the only place until now I am read about spinor space as a complex vector space, because of this i had a doubt about the statement.

(1) So complex vector space and spinor space are the same thing or spinor space are a particular case of a complex vector space?

(2) I am still don't found a book which make that connection (about spinor space and complex vector space) can you indicate me one?

thanks again
 
Hey davi2686.

You might want to look at the multiplication table / matrix structure to understand the algebra in specific detail.

It also helps to look at complex numbers in terms of Grassmann algebras (exterior/inner products and bi-vectors) and in the different high level complex number algebras in a variety of dimension and understanding the geometric meaning of how the multiplication tables correspond to rotations and scaling in a particular space.

The linear algebra decomposition of a space in terms of rotation, scaling, and possible translation can help visualize what is really going on.
