This gives errors in LaTeX (with AMS-Packages loaded)
\begin{equation}
  \label{eq:2.1}
  \left.\begin{parbox}{0.75\linewidth}
    \begin{enumerate}
    \item $T$ is a smooth open set with a $C^2$ boundary.
    \item $Y^*$ is locally on one side of $\pd T$ and\\
      $\pd T$ is a union of a finite number of segments if $n=2$\\
      or $\pd T$ is a union of a finite number of plane faces if $n >
      2$.
    \end{enumerate}
  \end{parbox}\right\}
\end{equation}

This is working fine:
\begin{equation}
  \label{eq:2.1}
  \left.\begin{minipage}{0.75\linewidth}
    \begin{enumerate}
    \item $T$ is a smooth open set with a $C^2$ boundary.
    \item $Y^*$ is locally on one side of $\pd T$ and\\
      $\pd T$ is a union of a finite number of segments if $n=2$\\
      or $\pd T$ is a union of a finite number of plane faces if $n >
      2$.
    \end{enumerate}
  \end{minipage}\right\}
\end{equation}

(and \pd defined with \partial).

Thank you very much for the hint using \boxed instead of \fbox in math mode!

(But please take into account that, if needed, one can parse width and 
position to a framebox when needed.)

Best regards
