Boltzmann Factor
Any term of the form e-
/τ is called a Boltzmann
Factor.
-
Gibbs Factor
Any term of the form e(Nμ-
)/τ is called a Gibbs factor.

Gibbs Sum
The Gibbs Sum is the sum of all of the Gibbs Factors for the states and numbers of a system, and is given by:
ZG(μ, τ) =
e(Nμ-
)/τ

Partition Function
The Partition Function represents the sum of all of the Boltzmann Factors for the states of a system, and is given by:
Z =
