Sorry I wasn't clear.  I am looking for all of the solutions where the
system is equal to zero.

[0		[equation for the derivatives dP1
0		dP2
0	= 	dP3
0		dP4
0]		dP5]

I hope this makes things clearer.

Katherine

Katherine,

I think you need to be more specific about what you want to do. It is
not clear what you mean by "the fixed points" of a system of
differential equations. Perhaps you mean the equilibrium/critical
points??
