Abstract
In the final version of the previously published article [1], the authors regret that the original contribution of the research conducted by Berezowski, [2] was not properly cited. In particular, the theoretical framework discussed in Sec. 2.2, for our model of Logistic equation with two delays [1]: dx/dt = −x(t) + ρx(t−1)*(1−x(t−2)), are mathematically identical (or substantially equivalent) for his model of Logistic equation with one delay, Sec. 2 [2]: σ*dx/dt + x(t) = a*x(t−τd)*(1−x(t−τd)) where τd is the delay time. . The omission was unintentional. The authors sincerely apologize to Prof. M. Berezowski and to the readership for this oversight. This correction does not affect the results or conclusions of the previous article.
