Harmonic analysis of harmonic functions in the plane [PDF]

Proceedings of the American Mathematical Society, 1976
A continuous function on the complex plane is harmonic if and only if the span of its compositions with entire functions is not dense in the space of continuous functions in the topology of uniform convergence on compact sets.

Accurate and Fast Parallelized Assessment of Waveform Distortions in Presence of Low and High frequency Spectral Components

, 2022
The waveforms distortion assessment nowadays requires great research efforts due to the contemporaneous presence of low- and high-frequency harmonics and interharmonics (up to 150 kHz). In this paper, a new multi-method approach allowed accurate and fast
