A New Formulation of Electrodynamics
A new formulation of electromagnetism based on linear differential commutator brackets is developed. Maxwell equations are derived, using these commutator brackets, from the vector potential $\vec{A}$, the scalar potential $\phi$ and the Lorentz gauge ...

Characterizations for the Riesz potential and its commutators on generalized Orlicz-Morrey spaces
In the present paper, we shall give a characterization for the Spanne and Adams type boundedness of the Riesz potential and its commutators on the generalized Orlicz-Morrey spaces, respectively.

A note on commutators of strongly singular Calderón-Zygmund operators
In this article, the authors consider the commutators of strongly singular Calderón-Zygmund operator with Lipschitz functions. A sufficient condition is given for the boundedness of the commutators from Lebesgue spaces Lp(Rn){L}^{p}\left({{\mathbb{R ...

Commutator identities on associative algebras and integrability of nonlinear pde's
It is shown that commutator identities on associative algebras generate solutions of linearized integrable equations. Next, a special kind of the dressing procedure is suggested that in a special class of integral operators enables to associate to such ...

Isometric endomorphisms of free groups [PDF]
An arbitrary homomorphism between groups is nonincreasing for stable commutator length, and there are infinitely many (injective) homomorphisms between free groups which strictly decrease the stable commutator length of some elements. However, we show in

Amphibious Generator via Mechanical Coupling for Versatile Energy Harvesting
An amphibious hybrid triboelectric nanogenerator–electromagnetic generator (TENG–EMG) efficiently harvests energy from wind and water. By integrating TENG and EMG units with a gear‐assisted mechanism, it enhances power output and powers small electronic devices.

Compactness of commutators of fractional integral operators on ball Banach function spaces
Let $ 0 < \alpha < n $ and $ b $ be a locally integrable function. In this paper, we obtain the characterization of compactness of the iterated commutator $ (T_{\Omega, \alpha})_{b}^{m} $ generated by the function $ b $ and the fractional integral ...

Fluctuation, dissipation, and thermalization in non-equilibrium AdS_5 black hole geometries
We give a simple recipe for computing dissipation and fluctuations (commutator and anti-commutator correlation functions) for non-equilibrium black hole geometries.
