I'm reading my lectures on TBM and I don't understand the following thing:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\omega(\overrightarrow k)=\omega_0-4t\cdot[\cos(k_xa/2)\cos(k_ya/2)+...][/tex]

It's related toFCCstructures, in which the number ofNearest Neighbors[tex](Z)[/tex] of an atom is equal to 12. Basically the three dots at the end leave me puzzled. What are they supposed to mean? Any help appreciated.
