Webanother operator called the adjoint of L, written Ly. What defines the adjoint is that, for any two vectors v 1;v 2, hLv 1;v 2i= hv 1;Lyv 2i: (6) This definition is a bit confusing because Lyis not explicitly constructed. You should think of this as “if I find an operator Lythat satisfies property (6), it must be the adjoint.” WebThe adjoint operator The bilinear identity The extended Green's identity The adjoint boundary conditions Incomplete systems Over-determined systems Compatibility under inhomogeneous boundary conditions Green's identity in the realm of partial differential operators The fundamental field operations of vector analysis Solution of incomplete ...
