I was calculating the Edwards-Anderson Hamiltonian of a Hopf link. A hopf link is like attachment 1. I have drawn the Seifert surface of that link. The surface is shown in attachment 2. It also contains the Boltzmann weight. So, this is an Ising model. I am confused as there are more than one interaction between a pair of sites. How will I keep that consideration when I calculate the Edwards-Anderson Hamiltonian.

Thanks in advance for your answers.

A quick supplementary question: should I model it as a frustrated Ising system?

Louis Kauffman advised me to just add the interactions up. –  Omar Shehab Feb 21 '13 at 5:49
