I have already asked this on the mathematics Stack exchange but I thought I'd try it here too!
The Hodge star operator ⋆ is a linear map between ⋀pV and ⋀n−pV for an inner product space V of dimension n.
So we can we write;
λ∈p⋀V
⋆λ∈n−p⋀V
- I am wondering is this the same operation as used in the Moyal bracket for functions in phase space?
Namely for two functions of the phase space f and g, the Moyal bracket is given by;
{f,g}:=1iℏ(f⋆g−g⋆f).
I think I'm wrong and that it is somehow a different operation with the same sign, but would really appreciate some help since I'm really not familiar with the Hodge operator other than what I have written above!
- Also if its not too much trouble, could anyone provide a bit of context to the Hodge star operation in physics? e.g. why should I really be interested in vectors in ⋀n−pV space?
