Asymptotic properties of Kneser type solutions for third order half-linear neutral difference equations [PDF]

open access: yesMiskolc Mathematical Notes, 2021
. The authors examine properties of positive solutions of the third order half-linear neutral difference equation where z n = y n + p n y σ ( n ) . They show that the positive solutions are in fact Kneser type solutions and they provide upper and lower ...
