Mechanistic Slumber vs. Statistical Insomnia: The early phase of Boltzmann's H-theorem (1868-1877) [PDF]

, 2011
An intricate, long, and occasionally heated debate surrounds Boltzmann's outstanding works on the H-theorem (1872) and the combinatorial interpretation of the second law (1877).

Ambarzumyan-type theorem for vectorial Sturm-Liouville operator with impulses

, 2023
We consider the vector-impulsive Sturm-Liouville problem with Neumann conditions. The Ambarzumyan$^{\textbf{,}}$s theorem for the problem is proved, which states that if the eigenvalues of the problem coincide with those of the zero potential, then the ...

A Liouville type theorem for p-Laplace equations

Electronic Journal of Differential Equations, 2015
In this note we study solutions defined on the whole space R^N for the p-Laplace equation $$ \hbox{div}(| \nabla u|^{p-2}\nabla u)+f(u)=0. $$ Under an appropriate condition on the growth of f, which is weaker than conditions previously considered ...

Spectral analysis of q-fractional Sturm-Liouville operators

Electronic Journal of Differential Equations, 2017
In this article, we study q-fractional Sturm-Liouville operators. Using by the functional method, we pass to a new operator. Then, showing that this operator is a maximal operator and constructing a self-adjoint dilation of the maximal dissipative ...
