Multiple minimality of the root vectors of polynomial operators bunch, perturbed by analytical operator-function $S (\lambda)$ с $S (\infty) = 0$ outside the circle
Для оператор-функции $L (\lambda) = I+L_0+\lambda L_1+ \dots + \lambda^n L_n+S(\lambda)$, где $I$ — тождественный оператор, действующий в сепарабельном гильбертовом пространстве, операторы $L_0,\dots,L_n$— вполне непрерывны, а оператор-функция $S(\lambda)$ аналитическая при $|\lambda |>\z...
