Abstract
We describe fluctuations in finite-size networks with a complex distribution of connections, We show that the spectrum of fluctuations of the number of vertices with a given degree is Poissonian. These mesoscopic fluctuations are strong in the large-degree region, where is the total number of vertices in a network), and are important in networks with fat-tailed degree distributions.
