New Class of Generalized Extensive Entropies for Studying Dynamical Systems in Highly Anisotropic Phase Space
Giorgio Sonnino, György Steinbrecher
Starting from the geometrical interpretation of the Rényi entropy, we introduce further extensive generalizations and study their properties. In particular, we found the probabilit…
On almost complex Lie algebroids
Cristian Ida, Paul Popescu
The almost complex Lie algebroids over smooth manifolds are introduced in the paper. In the first part we give some examples and we obtain a Newlander-Nirenberg type theorem on alm…
Reference Distribution Functions for Magnetically Confined Plasmas from the Minimum Entropy Production Theorem and the MaxEnt Principle, subject to the Scale-Invariant Restrictions
Giorgio Sonnino, Alessandro Cardinali, Gyorgy Steinbrecher +3
We derive the expression of the reference distribution function for magnetically confined plasmas far from the thermodynamic equilibrium. The local equilibrium state is fixed by im…
Derivation of Reference Distribution Functions for Tokamak-plasmas by Statistical Thermodynamics
Giorgio Sonnino, Alessandro Cardinali, Philippe Peeters +2
A general approach for deriving the expression of reference distribution functions by statistical thermodynamics is illustrated, and applied to the case of a magnetically confined…
The geometry of Lie algebroids and its applications to optimal control
Liviu Popescu
The paper presents the geometry of Lie algebroids and its applications to optimal control. The first part deals with the theory of Lie algebroids, connections on Lie algebroids and…
Transverse Killing and twistor spinors associated to the basic Dirac operators
Adrian Mihai Ionescu, Vladimir Slesar, Mihai Visinescu +1
We study the interplay between basic Dirac operator and transverse Killing and twistor spinors. In order to obtain results for general Riemannian foliations with bundle-like metric…
