Large enough bracket size

Question

$$\Sh(E/K)=\ker\textbraceleft WC(E/K)\rightarrow\prod_{\nu\in M_K}WC(E/K_{\nu})\textbraceright$$

How do I make my brackets larger than the \prod within it?

Answer 1

You can use the \left and \right commands to produce delimiters that will adjust to their content. For instance, to obtain curly brackets, you should use \left\{ and \rigth\} this way:

\[\Sh(E/K)=\ker \left\{ WC(E/K)\rightarrow\prod_{\nu\in M_K}WC(E/K_{\nu}) \right\} \]

(Notice that I changed $$ to \[ and \], as recommended)
