GreenFunction

GreenFunction[{ℒ[u[x]],ℬ[u[x]]},u,{x,xmin,xmax},y] gives a Green's function for the linear differential operator ℒ with boundary conditions ℬ in the range xmin to xmax. 

GreenFunction[{ℒ[u[x1,x2,…]],ℬ[u[x1,x2,…]]},u,{x1,x2,…}∈Ω,{y1,y2,…}] gives a Green's function for the linear partial differential operator ℒ over the region Ω.

GreenFunction[{ℒ[u[x,t]],ℬ[u[x,t]]},u,{x,xmin,xmax},t,{y,τ}] gives a Green's function for the linear time-dependent operator ℒ in the range xmin to xmax.

GreenFunction[{ℒ[u[x1,…,t]],ℬ[u[x1,…,t]]},u,{x1,…}∈Ω,t,{y1,…,τ}] gives a Green's function for the linear time-dependent operator ℒ over the region Ω.
