Spinor connection
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 … WebDefine spinor. spinor synonyms, spinor pronunciation, spinor translation, English dictionary definition of spinor. n.

WebMay 14, 2015 · The spinor representation decomposes into orbits under the action of the spin group (in a rather complicated way). 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. Webspinor bundles and fractional indices. (D) In ongoing work we try to use a string connection in order to define acovariant derivative on the stringor bundle. The main open questions one could then attack are: ICan one define a “Dirac” operator on sections of the stringor bundle? IWhat is the index of this operator, and does it compute the
