摘要
In our theoretical studies with replacement operators, we found the use of a graphical method very useful for operating with them. Now, for working with spin-orbital fermion operators, we have devised another easy graphical method which has proven to be very helpful to us. This method is presented here and as an example the square of the Hamiltonian operator is evaluated.
