Corrigendum to “Mathematical modelling of the semi-Markovian random walk processes with jumps and delaying screen by means of a fractional order differential equation” [Math. Meth. Appl. Sci. 41(18) (2018). https://doi.org/10.1002/mma.5328]

In the paper mentioned in the title, we studied the semi-Markovian random walk processes with jumps and delaying screen in zero. More precisely, we obtained a mathematical modeling of the semi-Markov random walk processes with a delaying screen in zero, given in general form by means of fractional differential equation. In this note, we provide a correction to some minor technicality in the proof of Theorem 2 in the aforementioned paper. © 2023 John Wiley & Sons, Ltd.
