This work based on the article of O. Blasco and T. Signes, where the o authors introduced
and studied the classes of bounded linear operators Φ : L (X,Y) → L (Z, W) such that
(Tn) → (Φ (Tn)) maps l
s
p
(X,Y) into lp (Z, W), l
s
p
(X,Y) into l
s
p
(Z, W) and l
w
p
(X,Y) into
l
s
p
(Z, W). The Pietsch-type dominations of (l
s
p
, lp)-summing linear operators wich presented
nowadays by José Rodríguez and Enrique A. Sánchez-Pérez is also given .
