I What kind of space is the space of spinors?

Hi, i dont 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

That is quite good sense actually - spinors form a vector space over the field of complex numbers... well done.

Thanks Simon Bridge, im already seen before the wikipedia article but is the only place until now im 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) Im still dont found a book which make that connection (about spinor space and complex vector space) can you indicate me one?

thanks again

See above - spinors are a special kind of vector.

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.
