On low-sampling-rate Kramers-Moyal coefficients
C. Anteneodo, S. M. Duarte Queiros
We analyze the impact of the sampling interval on the estimation of Kramers-Moyal coefficients. We obtain the finite-time expressions of these coefficients for several standard pro…
q-Generalization of the inverse Fourier transform
M. Jauregui, C. Tsallis
A wide class of physical distributions appears to follow the q-Gaussian form, which plays the role of attractor according to a Central Limit Theorem generalized in the presence of…
Describing the ground state of quantum systems through statistical mechanics
Andre M. C. Souza
We present a statistical mechanics description to study the ground state of quantum systems. In this approach, averages for the complete system are calculated over the non-interact…
Lyapunov exponent of the random frequency oscillator: cumulant expansion approach
C. Anteneodo, R. O. Vallejos
We consider a one-dimensional harmonic oscillator with a random frequency, focusing on both the standard and the generalized Lyapunov exponents, and respectively. We…
Love kills: Simulations in Penna Ageing Model
D. Stauffer, S. Cebrat, T. J. P. Penna +1
The standard Penna ageing model with sexual reproduction is enlarged by adding additional bit-strings for love: Marriage happens only if the male love strings are sufficiently diff…
On the Efficiency of Data Representation on the Modeling and Characterization of Complex Networks
Carlos A. Ruggiero, Odemir M. Bruno, Gonzalo Travieso +1
Specific choices about how to represent complex networks can have a substantial effect on the execution time required for the respective construction and analysis of those structur…
Time evolution towards q-Gaussian stationary states through unified Ito-Stratonovich stochastic equation
B. Coutinho dos Santos, C. Tsallis
We consider a class of single-particle one-dimensional stochastic equations which include external field, additive and multiplicative noises. We use a parameter which…
New representations of pi and Dirac delta using the nonextensive-statistical-mechanics q-exponential function
M. Jauregui, C. Tsallis
We present a generalization of the representation in plane waves of Dirac delta, , namely $δ(x)=(2-q)/(2π)\int_{-\infty}^\infty e_q^{…
A generalization of the cumulant expansion. Application to a scale-invariant probabilistic model
Antonio Rodriguez, Constantino Tsallis
As well known, cumulant expansion is an alternative way to moment expansion to fully characterize probability distributions provided all the moments exist. If this is not the case,…
Dynamics of tournaments: the soccer case
H. V. Ribeiro, R. S. Mendes, L. C. Malacarne +2
A random walk-like model is considered to discuss statistical aspects of tournaments. The model is applied to soccer leagues with emphasis on the scores. This competitive system wa…
