    • The emergence of self-organization in complex systems-Preface 

      Paradisi P.; Kaniadakis G.; Scarfone A.M. (Chaos, Solitons and Fractals, 2015-12-31)
      [No abstract available]
    • The M-Wright function as a generalization of the Gaussian density for fractional diffusion processes 

      Pagnini G. (Fractional Calculus and Applied Analysis, 2013-12-31)
      The leading role of a special function of the Wright-type, referred to as M-Wright or Mainardi function, within a parametric class of self-similar stochastic processes with stationary increments, is surveyed. This class ...
    • Topology of Spaces of Valuations and Geometry of Singularities 

      de Felipe Ana B. (Transactions of the AMS - American Mathematical Society, 2017-11-11)
      Given an algebraic variety X defined over an algebraically closed field, we study the space RZ(X,x) consisting of all the valuations of the function field of X which are centered in a closed point x of X. We concentrate ...
    • Turbulence and fire-spotting effects into wild-land fire simulators 

      Kaur I.; Mentrelli A.; Bosseur F.; Filippi J.-B.; Pagnini G. (Communications in Nonlinear Science and Numerical Simulation, 2016-01-01)
      This paper presents a mathematical approach to model the effects and the role of phenomena with random nature such as turbulence and fire-spotting into the existing wildfire simulators. The formulation proposes that the ...
    • Two-particle anomalous diffusion: Probability density functions and self-similar stochastic processes 

      Pagnini G.; Mura A.; Mainardi F. (Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2013-12-31)
      Two-particle dispersion is investigated in the context of anomalous diffusion. Two different modeling approaches related to time subordination are considered and unified in the framework of self-similar stochastic processes. ...
    • Universal bounds for large determinants from non-commutative Hölder inequalities in fermionic constructive quantum field theory 

      Bru J.-B.; de Siqueira Pedra W. (Mathematical Models and Methods in Applied Sciences (M3AS), 2017-08-02)
      Efficiently bounding large determinants is an essential step in non-relativistic fermionic constructive quantum field theory to prove the absolute convergence of the perturbation expansion of correlation functions in terms ...
    • Universal Bounds for Large Determinants from Non–Commutative Ho ̈lder Inequalities in Fermionic Constructive Quantum Field Theory 

      Bru J.-B.; de Siqueira Pedra W. (2016-01-01)
      Efficiently bounding large determinants is an essential step in non–relati- vistic fermionic constructive quantum field theory, because, together with the summability of the interaction and the covariance, it implies the ...
    • Velocity and energy distributions in microcanonical ensembles of hard spheres 

      Scalas E.; Gabriel A.T.; Martin E.; Germano G. (Physical Review E - Statistical, Nonlinear, and Soft Matter Physics, 2015-12-31)
      In a microcanonical ensemble (constant NVE, hard reflecting walls) and in a molecular dynamics ensemble (constant NVEPG, periodic boundary conditions) with a number N of smooth elastic hard spheres in a d-dimensional volume ...
    • Wildfire propagation modelling 

      Pagnini G.; Egorova V.; Trucchia A.; Mentrelli A.; Kaur I. (Geophysical Research Abstracts Vol. 20, 2018)
      Wildfires are a concrete problem with a strong impact on human life, property and the environment, because they cause disruption and are an important source of pollutants. Climate change and ...
    • Wildland fire propagation modeling: fire-spotting parametrisation and energy balance 

      Egorova V. N.; Pagnini G.; Trucchia A. (Proceedings of the 17th International Conference on Computational and Mathematical Methods in Science and Engineering, CMMSE 2017, pp. 805 - 813, 2017-07-04)
      Present research concerns the physical background of a wild-fire propagation model based on the split of the front motion into two parts - drifting and fluctuating. The drifting part is solved by the level set method and ...
    • Wildland fire propagation modelling 

      Egorova V. N.; Pagnini G.; Trucchia A. (MODELLING FOR ENGINEERING AND HUMAN BEHAVIOUR 2017 Extended abstract, 2017-12)
      Wildfire propagation modelling is a challenging problem due to its complex multi-scale multi-physics nature. This process can be described by a reaction- diffusion equation based on the energy balance principle. Alternative ...
