| Abstract: |
| Two delay difference equations of first order with continuous arguments Δτx(t)+pf(x(t-σ))=0,Δτx(t)+p(t)f(x(t-σ))=0 and related lemma were presented.Three results related with the distance of zeros in oscillatory solutions for the two equations were received. |
| Key words: delay difference equation oscillatory solution distance of zeros |
