4.3. Special Series
This is a brief listing of some of the most important series. Each of the convergence tests given in the previous section contains even more examples.
- Geometric Series

1 / 1-a, diverges otherwise converges absolutely for |a| <  1 to   
1 / 1-a, diverges otherwise
- p Series
 converges for p >  1, diverges otherwise converges for p >  1, diverges otherwise
