How do I cite my own PhD dissertation in a journal article?
In my experience (Theoretical Computer Science/Mathematical Logic) this issue is typically handled by having the sentence &quot;This article is based on Chapter X of the author's PhD thesis \cite{myThesis}.&quot; as a stand-alone paragraph at the end of the introduction section.
Having just the plain sentence is consistent with the article having been edited only minimally to turn a chapter into a stand-alone article. If there are substantial differences, these can be pointed out in addition. Eg &quot;We refer the reader to \cite{myThesis} for a much more detailed exposition of the proof.&quot;
