The geometric lower bound

Global wavefront containment, including every transition › The geometric lower bound · lines 986–997

One can also read the nonzero coefficient directly from (eq:Sgeom): a geometric branch has principal term

\frac{e ^{2 π i β k}}{4 π ^{2} ( R _{k} ^{2} - ( T - i 0 ) ^{2} )} .

Its character factor is never zero. Propagation avoids any need to select a leading term at a crossing of geometric fronts.
