In differential geometry and mathematical physics, a spin connection is a connection on a spinor bundle. It is induced, in a canonical manner, from the affine connection. It can also be regarded as the gauge field generated by local Lorentz transformations. In some canonical formulations of general relativity, a spin … See more Let $${\displaystyle e_{\mu }^{\;\,a}}$$ be the local Lorentz frame fields or vierbein (also known as a tetrad), which is a set of orthonormal space time vector fields that diagonalize the metric tensor See more Metricity It is easy to deduce by raising and lowering indices as needed that the frame fields defined … See more • Ashtekar variables • Dirac operator • Cartan connection • Levi-Civita connection See more In the Cartan formalism, the spin connection is used to define both torsion and curvature.

These orbits can be thought of as the possible "algebraic types" of spinors (in a point!), simlar to the (point-wise) rank of a symmetric $\binom02$-tensor field.
WebApr 3, 2024 · Spinor fields are considered in a generally covariant environment where they can be written in the polar form. The polar form is the one in which spinorial fields are expressed as a module times the exponential of a complex pseudo-phase, and in this form the full spinorial field theory can in turn be expressed by employing only real tensorial … WebWe offer long and short term support, 3-5 days a week, and can support individuals stepping down from the hospital or needing temporary support in addition to outpatient care.
