Hello,

I am new to Sage and I need to find the asymptotc form of the series coefficients of the following generating function:

GF (t,x,z) = (1 + tx - txz)/(1 - t - t^2x - txz + t^2xz)

Please help me.

Thanks a lot. Mohammad

Please help me.

F(t,x,z) = (1 + t*x - t*x*z)/(1 - t - t^2*x - t*x*z + t^2*x*z)

In other words, in the Taylor expansion of the function in terms of of the variable t, $t$, I am interested in the asymptotic form of the coefficient coefficient of the term t^Lx^Nz^B at $t^L\ x^N\ z^B$ in the limit of large L, N, $L$, $N$, and B.$B$.
