---> I realize that b_n is not a_n + a_(n+1), so forget this part.
When i make ratsum my idea was to project the rational function over the
vectorial space of telescopic rational functions and then use a suitable
decomposition
a_n = b_n + r_n with b_n telescopic and r_n not telescopic, looking for this
decomposition the above paper may give me somes ideas, because it suggest such
decomposition, so that a_n is telescopic iif r_n =0.
Perhaps this new decomposition can accelerate the algorithm for summation.
Well this is just a quick refletion nothing more.
Best regards.
