SUMMARY
The discussion centers on the evaluation of a sum in the context of the cosmological constant paper found at http://arxiv.org/pdf/1205.3365v1.pdf. The key argument is that as time approaches infinity with the substitution t = (1-iϵ)s, all terms in the sum S = ∑_n exp(-i E_n t) converge to zero except for the leading term associated with the lowest energy E_0. This is due to the rapid oscillation of the first term and the faster decay of subsequent terms, establishing that the dominant contribution to the sum is from the E_0 term.
