I have a question in the text book written by Weinberg, In page 232, (page 316 in the Japanese translation version), there is a following description. \\
The spin representations, for which $A+B$ is half an odd integer, can similarly be constructed from the direct product of these tensor representations and the Dirac representation $(\frac{1}{2}, 0)\oplus(0, \frac{1}{2})$. For instance, taking the direct product of the vector $( \frac{1}{2}, \frac{1}{2})$ representation and the Dirac $(\frac{1}{2}, 0)\oplus(0, \frac{1}{2})$ representation gives a spinor-vector $\Psi^{\mu}$, that transforms according to the reducible representation
\[ ( \frac{1}{2}, \frac{1}{2})\otimes [(\frac{1}{2}, 0)\oplus(0, \frac{1}{2})]=(\frac{1}{2},1)\oplus(\frac{1}{2},0)\oplus(1,\frac{1}{2})\oplus(0, \frac{1}{2}). \]
\\
There are not definitions of $\oplus$ and $\otimes$ in the text book, so I can't understand above equation. If you know the definitions, let me know. If you don't know, please ask members of your laboratory.

と出ます。ログの読み方を知らないので、どう直せばよいのかわからないのです。
なお、TeXは
簡単LaTeXインストールwindows編（２０１６年４月版）をダウンロードして使っています。私のPCのOSはwindows8.1です。
どう直したいかというと、添付ファイルの中の１行立ての式の中括弧を削除したファイルを作りたいです。
どうすればよいでしょうか？
