Properties of restrictions of the operator of multiplication by a continuous function
Для оператора А множення на неперервну функцію a(t) в просторі L2[0,b]=H, дано опис двох множин нескінченновимірних підпросторів нескінченної корозмірності: I(A)={N⊂H:A/N — ізоморфізм }, K(A)={M⊂H:A/M — компактне відображення}. Як приклад розглянуто питання про безумовну базисність послідовності {a...
