Seems that Summation can not be interchanged and the above is wrong. Sigh.
The following should work for numerical inputs (though gives no symbolic solution), using Maple's syntax:
1/A*t+ Sum((1)^n/(A^(n+1))*t^n*beta^n* Sum(t^(1k*(1eta))*beta^(k)*binomial(n,k)*(alpha*GAMMA(1eta))^k/GAMMA(2+nk*(1eta)), k = 0 .. n),n = 1 .. infinity)
I have not cared for the special case of eta = some positive integer.
