Hi,

I encountered some unfamiliar notation in a condensed matter problem:

Consider a screened potential of the form:
Vsc(r,t)=Veiqre-iwteat+c.c.

Could someone please explain to me the meaning of the term "c.c."? From the given context I can gather that it has something to do with swapping the sign of q and w, but I'd be grateful for a more precise definition.

Huh, should've figured that out myself, makes sense. Thanks!
