The Equivalence of Bernoulli's Equation and a Set of Integral Relations for Periodic Waves
Department of Mathematics, University of Edinburgh
In a recent paper Longuet-Higgins (1978) discovered some new relations between Stokes' coefficients in the theory of periodic gravity waves. These were shown to give rise to a set of integral relations. In this paper we show that this set is complete in the sense that it is equivalent to Bernoulli's equation. We also show that a suitably redefined set exists in the theory of the solitary wave.
