Tip:The number of rectangles is arbitrary—you can use as many, or as few, as you want. However, the more rectangles you use, the better the approximation will be to the actual area. Back to Top Example 2: Midpoint Riemann Sum Example question: Calculate a Riemann sum for f(x) = x...

(And no one, including Barrett, thinks that smooth continuum exists all the way in---Barrett refers to manifold model as only an approximation.) atyy said: The discussion (p10) of http://arxiv.org/abs/1101.6078 makes very interesting comments about the current models: "Diffeomorphism ...
This is allowed in the soft-photon approximation. On the other hand, terms k_i^2 could also be omitted in the soft-photon approximation, but they are kept because they render virtual photon integrals UV-finite. In the next step we perform the usual sum over permutation over all photons. ...
The trajectory of the pole position on the second Riemann sheet is displayed in Fig. 1. As expected from its quark content, the mass of the ρ increases if the pion becomes heavier. This behavior can be described to good approximation as a linear function in Mπ2 given by Mρ(Mπ2)=...
