<p>We study the partition function associated with the democratic formulation of M-theory, focusing on its global definition and quantum properties. Using a path integral representation that makes manifest the underlying cohomological structure, we analyze the coupled system of M-theory form fields (<i>A</i>₃ + <i>A</i>₆), and the background fields (<i>C</i>₄ + <i>C</i>₇), as well as their associated global transformations. We show that the resulting description is naturally captured by a Heisenberg-type group reflecting the presence of a quadratic coupling between electric and magnetic degrees of freedom. This framework provides a transparent characterization of the global structure of the theory, clarifies the role of higher-form global symmetry, and allows for a consistent definition of the partition function in terms of higher-dimensional auxiliary manifolds.</p>
