Another question about the use of the micro-canonical ensemble in deriving distributions.
On the Wikipedia-page the authors mention that the total volume of the system has to be constant.
See: https://en.wikipedia.org/wiki/Bose–Einstein_statistics#Derivation_from_the_microcanonical_ensemble
On the other hand this statement is not used as a constraint or in any other way that I can see.
In a way it would however make sense to introduce a volume constraint in order to make sure the system is closed.
If V is not constant (meaning W is not zero), but U is constant, then Q is not zero and the system is not closed (at least for an ideal gas).
Does anybody know about volume constraints in the microcanonical picture?
