Spinor group

WebJul 17, 2024 · I've been researching spinors, and I'm a bit confused by some of the terminology. In some cases, spinors seem to be presented as elements of the Spin group, whereas in others they seem to be presented as "vector-like" objects that transform under the Spin group (the latter seeming to be more common in physics settings). WebMar 20, 2024 · In fact this matrix is completely determined by the spinor in its first column. To see that the representation is really faithful let us compare the action of group elements when they act on our spinors. ( α − β ¯ β α ¯) ( z 1 z 2) = ( α z 1 − β ¯ z 2 β z 1 + α ¯ z 2) Now consider the other transformation: ( α − β ¯ β α ...
