The Abel-Plana formula gives an expression for the difference between a discrete sum and the corresponding integral. The formula can be derived from the argument principle
(1) |
where are the zeros of and are the poles contained within the contour . An appropriate choice of and then yields
(2) |
or equivalently
(3) |
The formula is particularly useful in Casimir effect calculations involving differences between quantized modes and free modes.
