V. B. Korotkov Sobolev Institute of Mathematics, Siberian Branch of the Russian Academy of Sciences, Novosibirsk
Abstract:
Given a positive linear operator $S\colon L_2\to L_2$ integral on some dense subspace in $L_2$, we prove that 0 belongs to the limit spectrum of $S$.
Keywords:
limit spectrum, positive operator, integral operator.
