Published in 2021 at "Mediterranean Journal of Mathematics"

DOI: 10.1007/s00009-021-01815-4

Abstract: In this paper, we present some fixed point theorems of Krasnosel’skii’s type in Banach spaces. The involved operators need not to be compact nor weakly continuous. The results are obtained and formulated with the use… read more here.

Published in 2017 at "Journal of Computational Electronics"

DOI: 10.1007/s10825-017-0993-8

Abstract: The calculation of plasma waves in a homogeneous quasi-2D electron gas is usually based on the Euler equation. It yields a dispersion relation with two branches, which are often referred to as Vlasov modes. Dyakonov… read more here.

Published in 2020 at "Journal of Fluid Mechanics"

DOI: 10.1017/jfm.2020.577

Abstract: Abstract Due to triboelectric charging, the solid phase in gas–particle flows can become electrically charged, inducing an electrical interaction among all the particles in the system. Because this force decays rapidly, many of the current… read more here.
