expression for 8(j)/8n on h in the usual "radiation" and "diffraction" problems may be 

 found in Newman, for instance. 



A classical technique for solving a potential-flow problem such as that defined 

 by Equations (2.7) through (2.10), in the general case of an arbitrary ship form, 

 consists in formulating an integral equation for the potential based on the use of 

 a Green function satisfying all the equations of the problem except the "hull boun- 

 dary condition," which is to be satisfied by means of the integral equation. The 

 required Green function is defined in the following section.
