Towards General Relativity as a generalized Yang-Mills theory
Hartwig Winterroth, Lorenzo Fatibene
As an application of the generalized principal bundle theory to covariant Lagrangian field theories, we aim at the development of an instance of generalized gauge theories, with th…
Lepage equivalents for second order Lagrangians and applications: modified higher order Boussinesq-type equations
Marcella Palese, Fabrizio Zanello
In the frame of the Lagrangian formalism on -order prolongations of fibered manifolds and related structures such as (prolongation of) projectable vector fields, (sheaves of) di…
Geometric theory of non-regular separation of variables and the bi-Helmholtz equation
Claudia M Chanu, Basel Jayyusi, Raymond G McLenaghan
The geometric theory of additive separation of variables is applied to the search for multiplicative separated solutions of the bi-Helmholtz equation. It is shown that the equation…
New Separation of Variables for the Classical XXX and XXZ Heisenberg Spin Chains
Guido Magnano, Taras Skrypnyk
We propose a non-standard separation of variables for the classical integrable XXX and XXZ spin chains with degenerate twist matrix. We show that for the case of such twist matrice…
Kinetic description of a Rayleigh Gas with annihilation
Alessia Nota, Raphael Winter, Bertrand Lods
In this paper, we consider the dynamics of a tagged point particle in a gas of moving hard-spheres that are non-interacting among each other. This model is known as the ideal Rayle…
On the Mean Residence Time in Stochastic Lattice-Gas Models
Marco Zamparo, Luca Dall'Asta, Andrea Gamba
A heuristic law widely used in fluid dynamics for steady flows states that the amount of a fluid in a control volume is the product of the fluid influx and the mean time that the p…
