Green's function
 

Dear all,

I am loking for a good introductory book about Green's functions, its derivation and use.

Thanks in advance

There is a book which I used alot for aeroacoustic applications: its title is "Green's functions", by G.F. Roach, Cambridge University Press (mine is 2nd ed.).

Thank you very much!

Re: Green's function
 

Roache book is good, and I had that as a text in a class on Green's Functions in grad school, but I found a more intuitive presentation in the chapter on Green's Functions in the book "Heat Conduction" by Necati Ozisik.

I found this useful beacuse the diffusion equation is so intuitive that the purpose of the Green's Function was manifeslty clear because like most readers of this forum, I already understood the mathematical details of the linear diffusion operator.

But having said that, I found the actual utility of the Green's Function to be less that one might think. First one has to find the appropriate Green's Function, and then use it. Although the Greesn's Function contains the "essence" of the operator, I found it often easier to simply code up the equations and let 'er rip...
