An important role is played by a function analytic in the open upper half - plane
and with positive imaginary part there . This function , called the characteristic
function of the pair , coincides with Krein ' s Q - function in the case where the ...

Now we consider a general inverse problem associated with Herglotz -
Nevanlinna functions . ... A Herglotz - Nevanlinna function N is the characteristic
function of a pair of selfadjoint operators if and only if conditions ( 4 . 13 ) and ( 4 .
14 ) are ...
