 Depending on the \emph{flux} $\Phi$ through the original plaquette it may be necessary to take $k\not=0$ in order to achieve the variational optimum. If $\phi$ is close to zero, however, we see that the total interpolated curvature of the subdivided plaquette scales as $\phi^2/n$. Thus we see that the flux $\Phi$ per plaquette undergoes the transformation $\Phi\mapsto \Phi^{\frac{1}{n}}$ under interpolation, i.e., the flux is simply divided into $n$ pieces and redistributed equally amongst the $n$ new plaquettes.
 
-Checking for consistency with the solution of Eq.~(\ref{eq:interpmin}) we find that, for $n=2$, we recover (for $k=0$) $A_1^\dag A_0 = U_0(U_0^\dag U_1^\dag)^{\frac{1}{2}}$ as expected from Eq. (\ref{eq:slerp}). As before, the $\su2$ solutions also apply when $G \cong \uone$, in which case $\eta = 1$, $\Phi = e^{i\phi} = U_{n-1}^\dag \dots U_0^\dag$, and $\mu^{jk} = e^{\frac{i2\pi jk}{n}}$.

 Suppose we have a regular lattice in two spatial dimensions. If we successively subdivide plaquettes $m$ times then the curvature \emph{per plaquette} in the refined lattice scales as $\phi^2/4^m$.  If we don't rescale lattice spacing this means that, as $m\rightarrow \infty$, the interpolated connection tends exponentially quickly to a flat connection.

 After the improved initial state is obtained we simply apply the quantum interpolation isometry to send the lattice spacing to zero. We are now guaranteed that infrared contributions to the correlation functions are well represented. Indeed, it follows that wilson loops now enjoy an area law scaling.

 The continuum hilbert space we describe here is known as a \emph{direct limit} of hilbert spaces; in the context we use it here we call this direct limit the \emph{semicontinuous limit} \footnote{This terminology was suggested to us by Vaughan Jones.} to indicate that it doesn't quite correspond to what we might demand of a full continuous quantum Yang-Mills theory. Note that the direct limit is a basic categorical construction (you can read about it further in, e.g., \cite{lang:2002a}). The application of the direct limit to hilbert spaces has a very long history; one early proposal to use the direct limit to model continuum limits can be found in \cite{bimonte_lattices_1996}, but there are surely prior proposals. A recent fascinating attempt to use the direct limit to build continuum limits of lattice theories, in particular, conformal field theories, can be found in \cite{jones_unitary_2014}.
 
-Let $\mathcal{D}$ be the directed set of regular partitions of $\mathbb{R}^d$ induced by integer lattices with lattice spacing $a$, i.e., $a\mathbb{Z}^d$. This set is directed by \emph{refinement}, i.e., a partition $Q$ is a \emph{refinement} of $P$, denoted $P\le Q$, if every element of $Q$ is a subset of an element of $P$. (A useful mnemonic to remember the ordering is that $Q$ has ``more'' elements than $P$.) We regard every lattice spacing $a$ as giving rise to a \emph{physically different} lattice.
