The real core model and its scales
1995
Annals of Pure and Applied Logic
Preserved Fulltext
This paper introduces the real core model K(R) and determines the extent of scales in this inner model. ...
K(R) is an analog of Dodd-Jensen's core model K and contains L(R), the smallest inner model of ZF containing the reals R. We define iterable real premice & and show that C, (. ...
We call R the set of reals and regard R as a topological space by giving it the product topology, using the discrete topology on CO. In this paper we study the inner model K(R), the real core model. ...

We derive the condition for core percolation and find that purely scale-free networks have no core for any degree exponents. ...
We also apply our theory to real-world directed networks and find, surprisingly, that they often have much larger core sizes as compared to random models. ...

We then solve exactly the bond percolation problem on the HRN model and produce fast and precise analytical estimates for the corresponding real networks. ...
The k-core decomposition of a network has thus far mainly served as a powerful tool for the empirical study of complex networks. We now propose its explicit integration in a theoretical model. ...
Adding clustering to the HRN is expected to shift its prediction toward higher values of T , i.e., closer to the results from the real network. ...
