On minimum number of distinct eigenvalues for a Stieltjes string problem on a tree
  Spectral problems are considered related to small vibrations of a tree of Stieltjes strings. It is shown that the minimum number of distinct eigenvalues of such a problem equals the maximal length (measured in number of point masses) of paths in the tree.    ...

Spectral problems are considered related to small vibrations of a tree of Stieltjes strings. It is shown that the minimum number of distinct eigenvalues of such a problem equals the maximal length (measured in number of point masses) of paths in the tree.
