Evolutionary game theory: Darwinian dynamics and the G function approach

Bukkuri, Anuraag; Brown, Joel S. - In: Games 12 (2021) 4, pp. 1-19

evolution of these individuals' strategies over time, we present the idea of a fitness-generating (G) function. Under this model … outline the differences between game theory and classical evolutionary game theory. We then introduce the G function framework …, deriving the model from fundamental biological principles. We introduce the concept of a G-function species, explain the …

A new RC and g-function hybrid model to simulate vertical ground heat exchangers

Maestre, Ismael Rodríguez; Gallero, Francisco Javier … - In: Renewable Energy 78 (2015) C, pp. 631-642

This paper presents a new hybrid two-dimensional model to simulate single U-tube ground heat exchangers based on the use of the electrical analogy to model heat transfer within the borehole and thermal response factors (short and long time-step g-functions) to estimate heat flow to the...

A hybrid reduced model for borehole heat exchangers over different time-scales and regions

Kim, Eui-Jong; Bernier, Michel; Cauret, Odile; Roux, … - In: Energy 77 (2014) C, pp. 318-326

Accurate modeling of heat transfer in the ground and inside the borehole is crucial to correctly size and assess performance of ground coupled heat pump systems. The model proposed here uses a hybrid approach combining two techniques. First, the rapid transient behavior inside the borehole is...

Confluent gamma density in modelling tsunami interevent times

Thomas, Naiju M. - In: Statistica 74 (2014) 1, pp. 113-123

We consider here a probability model which associates the usual gamma form with a confluent hypergeometric series. The probability model is termed as confluent gamma density. Some distributional properties of this model are derived. A graphical representation of the model for the varying values...

Generating random correlation matrices by the simple rejection method: Why it does not work

Böhm, Walter; Hornik, Kurt - In: Statistics & Probability Letters 87 (2014) C, pp. 27-30

We derive exact and asymptotic formulas for the probability that a symmetric n×n matrix with unit diagonal and upper diagonal elements i.i.d. uniform on (−1,1) is positive definite (and thus a “random correlation matrix”): this is almost never the case for n≥6.

On the distribution of exponential functionals for Lévy processes with jumps of rational transform

Kuznetsov, A. - In: Stochastic Processes and their Applications 122 (2012) 2, pp. 654-663

We derive explicit formulas for the Mellin transform and the distribution of the exponential functional for Lévy processes with rational Laplace exponent. This extends recent results by Cai and Kou [3] on the processes with hyper-exponential jumps.

Distribution of the product of determinants of noncentral bimatrix beta variates

Bekker, A.; Roux, J.J.J.; Ehlers, R.; Arashi, M. - In: Journal of Multivariate Analysis 109 (2012) C, pp. 73-87

The product moments of existing and new noncentral bimatrix variate beta distributions with bounded domain are derived. From these, exact expressions for the distributions of statistics are obtained by using the Mellin transform. These distributions add value to multivariate statistical analysis...
