On the functions of one selfadjoint integral operator
V. B. Korotkov Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences
Abstract:
We construct a selfadjoint Akhiezer integral operator $S$ on $L_2(-1,1)$ with the spectrum $\{-1;0;1\}$ and the property that every function $\varphi(S)$ that is not a multiple of $S$ fails to be an Akhiezer integral operator.
Keywords:
Akhiezer integral operator, function of a selfadjoint operator, spectral function.
