Dear Sir, I have compared ex13 and ex18, there is one thing confused me: in ex13, kpu and kup are different functions, but in ex18 there are the same functions, and I am wondering if the physic are correct in both cases. In general should we expect the kpu and kup are symmetric? Your clarification will be really appreciated. Fang (Cherry) Liu |
