Grassmann maths
WebThe motivation for departing from Grassmann’s point–based system and using vectors is the desire to introduce Grassmann’s ideas in the most familiar possible setting. The vector interpre- tation is more useful for applications in differential geometry and the point interpretation is more suited for projective geometry. Formally, let V be an n-dimensional complex vector space with basis . The Grassmann algebra whose Grassmann variables are is defined to be the exterior algebra of V, namely where is the exterior product and is the direct sum. The individual elements of this algebra are then called Grassmann numbers. It is standard to omit the wedge symbol when writing a Grassmann number once the definition is established. A general Grassmann number can be written as

WebIn QM, they are no longer Grassmann numbers, but operators instead. We choose ψ α ( x) to be Grassmann odd at the classical level so that the CCR (as induced by the Poisson bracket algebra) are anticommutators instead of commutators, thus giving rise to fermionic states. – AccidentalFourierTransform.
