Ending index or upper bound: infty

∫0∞Ω (e2πcΩ/a−1)−1 dΩ=a2/(24c2)\int_0^\infty \Omega\,(e^{2\pi c\Omega/a}-1)^{-1}\,d\Omega = a^2/(24c^2)
∞\infty

What this part means

This label says where the repeated addition, multiplication, or accumulation stops. It sets the last term or end of the range.

Its job in the formula

infty appears in the bound of this integral. The bound states where the repeated operation starts, ends, or which values it includes.

The passage around this formula

Write the normalized accelerated spectrum in terms of the dimensionless ratio u ≡\equiv cΩ\Omega/a , using the exact Bose-Einstein shape derived above. Carrying out the normalization integral, ∫0∞\int_0^\infty Ω\Omega\,(e2πcΩ/ae^{2\pi c\Omega/a}-1)^{-1}\,dΩ\Omega = a2a^2/(24c2c^2) , using the standard result ∫0∞\int_0^\infty x(exe^x-1)^{-1}dx=π2\pi^2/6 , gives the scale-family form
