Positive Lyapunov exponent of discrete analytic Jacobi operator

Electronic Journal of Differential Equations, 2017
In this article, we study the Lyapunov exponent of discrete analytic Jacobi operator with a family of some mappings on the torus. By applying the theory of subharmonic functions, we prove that the Lyapunov exponent is positive, if the coupling number ...

ON PLURIHARMONICITY CRITERIA OF HARMONIC AND \(\mathcal M\)-HARMONIC FUNCTIONS IN THE ARBITRARY BALL OF \({\mathbb C}^{n}\)

Ural Mathematical Journal
This paper introduces the concept of \({\mathcal M}\)-harmonic function in an arbitrary ball  of  \({\mathbb C}^{n}\) and proves some criteria for pluriharmonicity of harmonic functions in this ball.

Analysis of the cavitating flow induced by an ultrasonic horn – Numerical 3D simulation for the analysis of vapour structures and the assessment of erosion-sensitive areas

EPJ Web of Conferences, 2014
This paper reports the outcome of a numerical study of ultrasonic cavitation using a CFD flow algorithm based on a compressible density-based finite volume method with a low-Machnumber consistent flux function and an explicit time integration [15; 18] in

A Comparison Theorem for Subharmonic Functions [PDF]

Results in Mathematics, 2019
In this article, we prove an extension of the mean value theorem and a comparison theorem for subharmonic functions. These theorems are used to answer the question whether we can conclude that two subharmonic functions which agree almost everywhere on a surface with respect to the surface measure must coincide everywhere on that surface.

Competition between drift and topological transport of colloidal particles in twisted magnetic patterns

New Journal of Physics
We simulate the motion of paramagnetic particles between two magnetic patterns with hexagonal symmetry that are twisted at a magic angle. The resulting Morié pattern develops flat channels in the magnetic potential along which colloidal particles can be ...
