Spinor bundle
Given a
differentiable manifold with a
tetrad of signature (p,q) over it (see
tetrad for notation and prelimenaries), a
spinor bundle over M is a
vector SO(p,q)-bundle over M such that its
fiber is a
spinor representation of Spin(p,q) (the
double cover of SO(p,q) ). Actually, when p+q <= 3, we can have more interesting bundles like anyonic bundles!
Spinor bundles inherit a connection from a connection on the vector bundle V (see tetrad).
