Cycle (Map)
An 
-cycle is a finite sequence of points 
, ..., 
such that, under a Map 
,
 |  |  | |
 | |  | |
 | |  | |
 | |  |
In other words, it is a periodic trajectory which comes back to the same point after
iterations of the cycle. Everypoint 
of the cycle satisfies 
and is therefore a Fixed Point of the mapping 
. A fixedpoint of is simply a Cycle of period 1.- Survivorship Curve
