The phenomenon of six degrees of separation is an old but attractive subject. The deep understanding has been uncovered yet, especially how closed pa…

The evolution of cooperation among unrelated individuals in human and animal societies remains a challenging issue across disciplines. It is an impor…

We reformulated the string formalism given by Aoyama, using an adjacent matrix of a network and introduced a series of generalized clustering coeffic…

We introduce a series of generalized clustering coefficients based on String formalism given by Aoyama, using adjacent matrix in networks. We numeric…

On the basis of quantum field theory, we consider a unified description of various processes accompanied by neutrinos, namely weak decays and oscilla…

In this article we discuss six degrees of separation, which has been suggested by Milgram's famous experiment\cite{Milg},\cite{Milg2}, from a theoret…

Milgram Condition proposed by Aoyama et al. plays an important role on the analysis of "six degrees of separation". We have shown that the relations …

Braess \cite{1} has been studied about a traffic flow on a diamond type network and found that introducing new edges to the networks always does not …

We study the effect of the network topology to propagation phenomena on networks in this article. We do not assume any propagation model such as the …

In this article, I propose a systematic method for the inverse ultra-discretization of cell automata using a functionally complete operation. We deri…

In this article we discuss six degrees of separation, which has been proposed by Milgram, from a theoretical point of view. Simply if one has $k$ fri…

The phenomenon of six degrees of separation is an old but interesting problem. The considerations of the clustering coefficient reflecting triangular…
