This paper presents a coordinate free pre-metric formulation of charge free Maxwell-Minkowski electrodynamics, and of the developed by the authors non-linear Extended Electrodynamics. First we introduce some formal relations from multilinear algebra

This paper aims to relate some properties of photon-like objects, considered as spatially finite time-stable physical entities with dynamical structure, to well defined properties of the corresponding electromagnetic strains defined as Lie derivative

We use the transfer-matrix approach to solve the one-dimensional Schrodinger equation for a particular family of structured barriers and to compute in an explicit form the abovebarrier and subbarrier transmission coefficients as functions of barrier

This paper extends the ideas of Donev & Tashkova (1993) to a relativistic nonlinearization of the classical Maxwell theory in the continuous medium case. The field here is described by a 2-form on Minkowski space with values in a two-dimensional vect

This paper aims to present a general idea for description of spatially finite physical objects with a consistent nontrivial translational-rotational dynamical structure and evolution as a whole, making use of the mathematical concepts and structures

We work out the general idea that a composite continuous physical system can be mathematically modelled locally as a completely integrable geometric distribution on a manifold, the time-recognizable subsystems to be modelled by corresponding subdistr

In the present paper we give a brief study of the observed homology properties of the standard electromagnetic stress‐energy‐momentum tensor in the important case of null fields, i.e., when the two invariants I1 = 12FμνFμν and I2 = Fμν(*F)

This paper sets the problem of building a mathematical model of the pure electromagnetic field as composed by non-interacting strictly 3-localized finite solutions of some nonlinearization of pure field Maxwell’s equations. As a first step in this
