ABSTRACT
Consider the first-order nonlinear neutral differential equations () d d t [ x ( t ) − h ( t ) x ( τ ( t ) ) ] + ∑ i = 1 n p i ( t ) f i ( x ( g i ( t ) )) = 0 https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003067498/6ba0c26b-f086-40cc-86ed-1693dc596221/content/eq1266.tif"/>
