Query: On the indecomposability in the category of representations of a quiver
  and in its subcategory of orthoscalar representations   One can regard the category of represenations of quivers in Hilbert spaces as
a subcategory in the category of all representations, and at that objects,
which are indecomposable in the subcategory, become in general decomposable in
the ``larger'' category. We prove that it does not happen with indecomposable
locally scalar representations of a quiver.
