Hi
the following works nicely

\begin{dmath}
\label{eq:sec4-proof:17}
H^n-H^0 = \frac{\partial A^a}{\partial U}(U^n)DU^n \partial_aU^{n}-\frac{\partial A^a}{\partial U}(U^0)DU^0 \partial_aU^{0}
= DU^n \partial_a \left(\frac{\partial A^a}{\partial U}(U^n)-\frac{\partial A^a}{\partial U}(U^0)\right)
+ \frac{\partial A^a}{\partial U} \left( DU^n \partial_a U^n - DU^0 \partial_aU^0
\right)
= H_1+H_{2}
\end{dmath}

but that one not

\begin{dmath}
\label{eq:sec4-proof:17}
H^n-H^0 = \frac{\partial A^a}{\partial U}(U^n)DU^n \partial_aU^{n}-\frac{\partial A^a}{\partial U}(U^0)DU^0 \partial_aU^{0}
= DU^n \partial_a \left(\frac{\partial A^a}{\partial U}(U^n)-\frac{\partial A^a}{\partial U}(U^0)\right)
+ \frac{\partial A^a}{\partial U} \left( DU^n \partial_a U^n - DU^0 \partial_aU^0
\right)
=: H_1+H_{2}
\end{dmath}

the issue is to consider =: in a similar way as =
I tried {=:} but it did not work as expected.

thanks for the nice package
