 In the field of cliodynamics, Korotayev has developed a number of mathematical models of interaction between the very long-term, "millennial" hyperbolic trend dynamics of social systems and the shorter-term, "secular" (that is, observed at the scale of centuries), cyclical dynamics.He has also produced a number of mathematical models describing specifically long-term political-demographic dynamics of Egypt and used them for a demographic structural analysis of the 2011 Egyptian Revolution.Korotayev was one of the first to predict and assess the June 2013 Egyptian protests.
