The following differential equation u(n)(t)+p(t)|u(σ(t))|μ(t) sign u(σ(t))=0 is considered. Here p∈Lloc(R+;R+), μ∈C(R+;(0,+∞)), σ∈C(R+;R+), σ(t)≤t, and limt→+∞σ(t)=+∞. We say that the equation is almost linear if the conditi

We consider a difference equation$$ \varDelta u(k)+\sum \limits_{i-1}^m{p}_i(k)\;u\left({\tau}_i(k)\right)=0, $$ where m ϵ N, the functions, pi : N → R+ and τi : N → N, limk → + ∞τi(k) = + ∞ , τi(k) ≤ k − 1, i = 1, …, m, are defin
