Latex 中带有花括号的奇怪错误

我无法解决这个问题。我写道：

$[i\delta, 1/2\sqrt{3}+i(1+2\delta)/2}]$ and $[i(1+\delta), 1/2\sqrt{3}+i(1+2\delta)/2]$

背面写着：

 Extra }, or forgotten $.

l.210 ...ts $[i\delta, 1/2\sqrt{3}+i(1+2\delta)/2}
                                                  ]$ and $[i(1+\delta), 1/2\...
I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.

这段文字有什么问题？我觉得它完全没问题。

在第一个数学部分的末尾放置了一个不需要的右花括号，即$[i\delta, 1/2\sqrt{3}+i(1+2\delta)/2} ]$，它没有匹配的左花括号，请将其删除，然后尝试相同操作......
