    I have added (here) statement and proof of the “extension lemma” following Griffiths & Morgan 2013

    together with a paraphrasing of their remark (here) that the extension lemma also holds for smooth differential forms on nn-simplices

    finally followed by a further remark that, thus, the extension lemma also holds for smooth forms on extended simplices (as they appear in the simplicial formula for the shape modality)

    (since in Griffiths & Morgan’s proof the bound on the barycentric coordinates for simplices plays no role).
