Why is it not possible to have Weyl spinors in odd dimensions?
Vile spinors are mathematical objects that belong to the category of Clifford algebras. They are a specific type of spinor that is defined in odd dimensions and are used in various fields of physics and mathematics, including string theory and differential geometry.
Vile spinors are closely related to other types of spinors, such as Weyl and Majorana spinors. In fact, they can be obtained from Weyl spinors by applying a specific transformation known as the Majorana condition. Additionally, they are also related to other mathematical objects such as Dirac spinors and Clifford algebras.
Vile spinors have several properties that make them useful in theoretical physics and mathematics. One of their key properties is that they transform under the Lorentz group in a specific way, making them useful for describing particles with spin in odd dimensions. They also have a specific charge conjugation property that is important in various quantum field theories.
In string theory, vile spinors are used to describe the fermionic degrees of freedom of the fundamental strings. They play a crucial role in the construction of supersymmetric string theories, which are important models for unifying quantum mechanics and general relativity. They are also used in the study of anomalies and dualities in string theory.
Yes, vile spinors are only defined and used in odd dimensions. This is because in even dimensions, there are other types of spinors that are more convenient to work with, such as Dirac and Majorana spinors. In odd dimensions, however, vile spinors are the only type of spinor that can be constructed from Weyl spinors, making them an important mathematical object in those dimensions.
