I am writing a document in "Report" style. Throughout the document, results in Chapter X and Section Y appears as: "Theorem X.Y.1" or "Lemma X.Y.2" etc. I want to keep that this way.
However my first Chapter, that serves as an introduction, doesn't contain any Section. Thus results appear as: "Theorem 1.0.1" or "Lemma 1.0.2". This is annoying, and I would like to see these results as "Theorem 1.1" or "Lemma 1.2" instead.
Is it possible to do that without leaving the "Report" style?
