Green's first identity
WebHere, the tool that we used is the divergence theorem (with which is actually derived the Green's first identity). Note that the surface integral is 0 because v is zero on ∂ Ω (to be more speciffic, it is zero in the trace sense). WebMay 2, 2012 · 1) This result can be verified by expanding the divergence of a vector times a scalar for the two addends on the RHS. The condition imposed by Helmholtz equation ∇ 2 𝐏 = − 𝑘 2 𝐏 can be readily incorporated in the present formulation of Green’s second identity. This result is particularly useful if the vector fields satisfy the ...
