A theoretical approach for Pareto-Zipf law Tuncay, Çağlar (World Scientific Pub Co Pte Lt, 2008-08-01) We suggest an analytical approach for the Pareto-Zipf law, where we assume random multiplicative noise and fragmentation processes for the growth of the number of citizens of each city and the number of the cities, respect...
Model of world: Her cities, languages and countries Tuncay, Çağlar (2008-03-01) The time evolution of Earth with her cities, languages and countries is considered in terms of the multiplicative noise(1) and the fragmentation processes, where the related families, size distributions, lifetimes, bilingu...
A new model for competition between many languages Tuncay, Çağlar (World Scientific Pub Co Pte Lt, 2007-07-01) Time evolution of number of cities, population of cities, world population, and size distribution of present languages are studied in terms of a new model, where population of each city increases by a random rate and decre...
Formation of languages; Equality, hierarchy and teachers Tuncay, Çağlar (World Scientific Pub Co Pte Lt, 2007-06-01) A quantitative method is suggested, where meanings of words, and grammatic rules about these, of a vocabulary are represented by real numbers. People meet randomly, and average their vocabularies if they are equal; otherwi...
Opinion dynamics driven by leaders, media, viruses and worms Tuncay, Çağlar (World Scientific Pub Co Pte Lt, 2007-05-01) A model on the effects of leader, media, viruses, worms, and other agents on the opinion of individuals is developed and utilized to simulate the formation of consensus in society and price in market via excess between sup...
Power laws and Gaussians for stock market fluctuations Tuncay, Çağlar (Elsevier BV, 2007-01-15) The daily financial volume of transaction on the New York Stock Exchange and its day-to-day fluctuations are analysed with respect to power-law tails as well to their long-term trends. We also model the transition to a Gau...
Stock mechanics: A general theory and method of energy conservation with applications on DJIA Tuncay, Çağlar (World Scientific Pub Co Pte Lt, 2006-11-01) A new method, based on the original theory of conservation of sum of kinetic and potential energy defined for prices is proposed and applied on the Dow Jones Industrials Average (DJIA). The general trends averaged over mon...
Socioeconophysics: Opinion dynamics for number of transactions and price, a trader based model Tuncay, Çağlar (World Scientific Pub Co Pte Lt, 2006-10-01) Involving effects of media, opinion leader and other agents on the opinion of individuals of market society, a trader based model is developed and utilized to simulate price via supply and demand. Pronounced effects are co...
Stock mechanics: predicting recession in S&P500, DJIA and NASDAQ Tuncay, Çağlar (2006-03-01) Proposed in this paper is an original method assuming potential and kinetic energies for prices and for the conservation of their sum that has been developed for forecasting exchanges. Connections with a power law are show...
