This command generates the summation operator,

. The difference between this and `\Sigma`

, which generates the capital letter

, is that `\sum`

appears larger, and that it supports the limits to be displayed below and above the symbol.

The following example illustrates the difference between `\sum`

and `\Sigma`

.

This examples are written as:

```
1 \sum_{n=1}^\infty
2 \qquad
3 \Sigma_{n=1}^\infty\frac{1}{2^n}=1
```
