A Stirling number Snk is definedc as the number of ways of partitioning the set of positive numbers (1,2,3,....n) into k non empty subsets. We can show that by considering if the singleton subset (n) is a partition or not that Snk = Sn-1, k-1 + kSn-1,k Another recurrence relation comes from considering the number of partit

Observe that (0,0) is a fixed point of the system: x_(n+1) = u*x_n - y_n + (y_n)^2 y_(n+1) = x_n + (x_n)^4 + y_n Regardless of the choice of parameter u. Determine the range of u values for which this fixed point is stable.
Solve the recurrence relation x_(n+1) = x_n + x_(n-1), x_0 = 1, x_1 = 1. That it, find a formula for x_n in terms of n
