On the averaging method for differential equations with delay. <i>Electronic Journal of Differential Equations, 2002</i>(65), pp. 1-16.1072-6691https://hdl.handle.net/10877/12398In this paper, we present averaging results for delay differential equations under weak conditions. The main result is formulated in both classical mathematics and nonstandard analysis. It is proved with internal set theory which is an axiomatic description of nonstandard analysis.Text16 pages1 file (.pdf)enAttribution 4.0 InternationalAveraging methodDifferential equations with delayNonstandard analysisArticle
