Аннотация
Let E and F be Banach spaces. A linear operator from E to F is said to be strictly singular if, for any subspace Q ⊂ E, the restriction of A to Q is not an isomorphism. A compactness criterion for any strictly singular operator from Lp to Lq is found. There exists a strictly singular but not superstrictly singular operator on Lp, provided that p ≠ 2.
