Creole Viewed from Population Dynamics

Creole is one of the main topics in various fields concerning the language origin and the language change, such as sociolinguistics, the developmental psychology of language, paleoanthropology and so on. Our purpose in this paper is to develop an evolutionary theory of language to study the emergence of creole. We discuss how the emergence of creole is dealt with in the perspective of populatio...

The View from Above

Evolution viewed from physics, physiology and medicine.

Stochasticity is harnessed by organisms to generate functionality. Randomness does not, therefore, necessarily imply lack of function or 'blind chance' at higher levels. In this respect, biology must resemble physics in generating order from disorder. This fact is contrary to Schrödinger's idea of biology generating phenotypic order from molecular-level order, which inspired the central dogma o...

Energy Balance Models - Viewed from Stochastic Dynamics

In this article the bottom part in the hierarchy of climate models-energy balance models-are revisited by a mathematician working in stochas-tic dynamics. The review of mostly deterministic 0-to 2-dimensional models focuses on the mathematical problems of equilibria, stability and bifurcations. Stochastic extensions can proot from the availability of well developed mathematical theories. To giv...

Congestion games viewed from M-convexity

Congestion games have extensively been studied till recently. An interesting special class of congestion games on networks is the class of congestion games on extension-parallel networks considered by Holzman and Law-yone (2003). It is shown by Fotakis (2010) that for every congestion game on an extension-parallel network, any best-response sequence reaches a pure Nash equilibrium of the game i...
