Diagrams of the regions in the Aslamazov–Larkin contribution to the thermal conductivity. By taking into account all their possible combinations in pairs, the AL diagrams for a granular system can be constructed by means of the shown regions. Diagram (b) has a double multiplicity since the bare tunnel vertex can stay on both sides of the region.
