It is my great pleasure to give a talk at the Martin Glicksman Festival. The work which I was going to present here was published recently [1], and I decided to shift the discussion to the motivation of this work, which seems more interesting than the work itself. It is gradually being recognized in various branches of physics that the macroscopic description of solids requires “new thermodynam...

The thermodynamical property of a small cluster including M Hubbard dimers, each of which is described by the two-site Hubbard model, has been discussed within the nonex-tensive statistics (NES). The temperature dependence of the energy, entropy, specific heat and susceptibility has been calculated for M = 1, 2, 3 and ∞ (corresponding to q = 1) with the use of the relation between the entropic ...

We express the idea of classical competition in a statistical equilibrium model, where the tendency for competition to equalize profit rates results in an exponential power (or Subbotin) distribution. The model supports and extends recent evidence on the Laplace distribution of growth rates in firm size. We also find tent-shaped distributions in the size growth rates of Forbes Global 2000 compa...

This paper presents the use of fuzzy inference to provide a viable modeling and simulation methodology for the estimation of population growth in any country or region. The study is motivated by the classical complex and time-consuming growth modeling and prediction methods. The related design issues are presented and the fuzzy inference model for population growth is derived. The human social ...

today, stock investment has become an important mean of national finance. apparently, it is significant for investors to estimate the stock price and select the trading chance accurately in advance, which will bring high return to stockholders. in the past, long-term trading processes and many technical analysis methods for stock market were put forward. however, stock market is a nonlinear sys...
