Approximating time to extinction for endemic infection models

, 2017
Approximating the time to extinction of infection is an important problem in infection modelling. A variety of different approaches have been proposed in the literature.

Extreme Value Laws for Superstatistics

, 2014
We study the extreme value distribution of stochastic processes modeled by superstatistics. Classical extreme value theory asserts that (under mild asymptotic independence assumptions) only three possible limit distributions are possible, namely: Gumbel,

Reaction-diffusion with a time-dependent reaction rate: the single-species diffusion-annihilation process

, 2004
We study the single-species diffusion-annihilation process with a time-dependent reaction rate, lambda(t)=lambda_0 t^-omega. Scaling arguments show that there is a critical value of the decay exponent omega_c(d) separating a reaction-limited regime for ...

Asymptotic Behaviour of the Proper Length and Volume of the Schwarzschild Singularity

, 2010
Though popular presentations give the Schwarzschild singularity as a point it is known that it is spacelike and not timelike. Thus it has a "length" and is not a "point". In fact, its length must necessarily be infinite.

Evidence of exactness of the mean field theory in the nonextensive regime of long-range spin models

, 1999
The q-state Potts model with long-range interactions that decay as 1/r^alpha subjected to an uniform magnetic field on d-dimensional lattices is analized for different values of q in the nonextensive regime (alpha between 0 and d).

Non-vanishing boundary effects and quasi-first order phase transitions in high dimensional Ising models

, 2010
In order to gain a better understanding of the Ising model in higher dimensions we have made a comparative study of how the boundary, open versus cyclic, of a d-dimensional simple lattice, for d=1,...,5, affects the behaviour of the specific heat C and ...

Boltzmann-type models with uncertain binary interactions

, 2017
In this paper we study binary interaction schemes with uncertain parameters for a general class of Boltzmann-type equations with applications in classical gas and aggregation dynamics.

Asymptotic freedom from induced gravity cosmology

, 1996
We give conditions to obtain cosmological asymptotic freedom in scalar-tensor theories of gravity. We show that this feature can be achieved in FRW flat spacetimes since we obtain singularity free solutions where the effective gravitational constant $G_ ...
