Abstract It has long been recognized that diversity has many measurable aspects, such as richness, evenness, and similarity among species. However, given a diversity index, it is unclear whether it necessarily can be decomposed into components that r

We investigate the connection between the existence of an explicit travelling wave solution and the travelling wave with minimal speed in a scalar monostable reaction-diffusion equation.

We discuss equilibrium conditions for heterogeneous substances subject to electrostatic or magnetostatic effects. We demonstrate that the force-like aleph tensor ℵij and the energy-like beth tensor ℶij for polarizable deformable substances are di

We employ the Pade approximation to derive a set of new partial differential equations, which can be put forward as possible models for phase transitions in solids. We start from a nonlocal free energy functional, we expand in Taylor series the inter

We combine Gibbsian method thermodynamic method for heterogeneous systems with electrostatics. The substances under study are those able to accumulate free (i.e., not dipolar) electric charges. We announce several key formulas related to the first an

We show that the ubiquitous formula for ponderomotive forces due to a distribution of a polarized substance implies a non-vanishing self-force. This constitutes a striking paradox since this prediction is in startling contrast with observed phenomena

In the classical textbook (Landau and Lifshitz, 1963), Landau and Lifshtz suggested their version of the famous Thomson variational principle (a.k.a Thomson theorem.) So far, their version has not gained the interest it deserves, either among physici
