Partial Differential Equations and Strictly Plurisubharmonic Functions in Several Variables

open access: yesExtracta Mathematicae, 2018
Using algebraic methods, we prove that there exists a fundamental relation between partial differential equations and strictly plurisubharmonic functions over domains of Cn (n ≥ 1).

Characterization of mean value harmonic functions on norm induced metric measure spaces with weighted Lebesgue measure

open access: yesElectronic Journal of Differential Equations, 2020
We study the mean-value harmonic functions on open subsets of~$\mathbb{R}^n$ equipped with weighted Lebesgue measures and norm induced metrics. Our main result is a necessary condition stating that all such functions solve a certain homogeneous system

REDUCED p-MODULUS, p-HARMONIC RADIUS AND p-HARMONIC GREEN’S MAPPINGS

open access: yesПроблемы анализа, 2018
We consider the definitions and properties of the metric characteristics of the spatial domains previously introduced by the author, and their connection with the class of mappings, the particular case of which are the harmonic Green’s mappings ...

Characterizing Level-set Families of Harmonic Functions

open access: yes, 2019
Families of hypersurfaces that are level-set families of harmonic functions free of critical points are characterized by a local differential-geometric condition.

Power system harmonic detection based on cubic spline function and Rife-vincent self-convolution window interpolation FFT algorithm

open access: yesDianzi Jishu Yingyong, 2018
When using the Fast Fourier Transform(FFT) to perform harmonic analysis on power systems, due to asynchronous sampling and data truncation, fence effect and spectrum leakage will occur, and accurate harmonic parameters cannot be obtained.
