\Phi _B = \oint_\Sigma \mathbb{B}\cdot d\Sigma = \oint_\Sigma (\nabla \times \mathbb{A}) \cdot d\Sigma
where \mathbb{A} is written in terms of the Berry connection,
\mathbb{A} = i \langle \psi_n \mid \nabla _R \mid \psi_n \rangle
and noting the relation to Berry's geometric phase,
\gamma (t) = i \int \langle \psi_n \mid \nabla_R \mid \psi_n \rangle \cdot d\mathbb{R}
Given \mathbb{B} = \nabla \times \mathbb{A}
\mathbb{B} = i \nabla_R \times \langle \psi_n \mid \nabla_R \mid \psi_n \rangle
and Gauss's Theorem,
\Phi _B = \oint_\Sigma \mathbb{B}\cdot d\Sigma = \int \int \int_V (\nabla \cdot \mathbb{B} ) dV
By the gHH the volume in \mathbb{R}^3 is arbitrarily small, so the divergence theorem applies, and passing the imaginary i over the Del,
\nabla_R \cdot \mathbb{B} = i \nabla_R \cdot \nabla_R \times \langle \psi_n \mid \nabla_R \mid \psi_n \rangle
since the vector identity of the triple vector product of \mathbb{A},
\nabla \cdot \nabla \times \mathbb{A} = 0
reduces the divergence of \mathbb{B} to,
\nabla_R \cdot \mathbb{B} = i \nabla_R \cdot \nabla_R \quad \times \langle \psi_n \mid \nabla_R \mid \psi_n \rangle = 0
so the magnetic flux,
This proves that no isolated magnetic flux could exist in the context of the inflationary period of the Big Bang and since an isolated magnetic flux is the definition of a magnetic monopole:
Therefore the principle of Revolution of Matter predicts that no magnetic monopoles could evolve during the Big Bang.
