Abstract
Conditions under which solutions of a firstorder nonlinear variabledelay dynamic
equation go to zero at infinity are given, for arbitrary time scales that are unbounded
above. In two examples, we apply our techniques to dynamic equations on isolated,
unbounded time scales.
AMS subject classification: 39A10.
Keywords: Delay dynamic equation, time scale, attractivity.
