        It asks for ntheorem.sty.

        It asks for dsfonts.sty. One more question: how can I insert
calligraphic, hand-written-like capital letters? And gothic letters?
        Anyway, I think that the symbols for the five sets above, together
with a special H (for quaternions), Ca (for Cayley's octaves) and a
calligraphic P (for the set of all subsets of a given set), ought to be
found in the default menus, as they are very common in various branches
of mathematics. Please think about including them in future versions.

        Until I have time to browse through your lyx guide, where should I
get the 2 files above from?

        a.
