WebThe first part of Zeckendorf's theorem (existence) can be proven by induction. For n = 1, 2, 3 it is clearly true (as these are Fibonacci numbers), for n = 4 we have 4 = 3 + 1. If n is a Fibonacci number then we're done. Else there exists j such that Fj < n < Fj + 1 . WebGreen's theorem Remembering the formula Green's theorem is most commonly presented like this: \displaystyle \oint_\redE {C} P\,dx + Q\,dy = \iint_\redE {R} \left ( \dfrac {\partial …

WebGreen's function reconstruction relies on representation theorems. For acoustic waves, it has been shown theoretically and observationally that a representation theorem of the correlation-type leads to the retrieval of the Green's function by cross-correlating fluctuations recorded at two locations and excited by uncorrelated sources.
