COMMENTS

If signed, a=11/2+1/31/4+1/5.... is a constant "not too far" from log2=0.69315.
With transform in A100597, A129891 or A130620, the corresponding polynomial family has roots along a curve which is to compare to fig 2 of P. Flajolet, X. Gourdon, B.Salvy, Gazette des Mathematiciens 1993, 55, pp. 6778.
