Hi all,

May I get help in how to label system of equations?

I usually use the following

\begin{equation}\label{eqn:TW}

\begin{split}

u_{t}& =u_{xx}+f(u,v),\\

v_{t}& =g(u,v),

\end{split}

\end{equation}

I would like here to get a lebel but not number as usual I want it something different. For example, instead of getting (1) I would like to get (TW) as a lebel.

Any help will be greatly appreciated.

Thank you in advance.
