Positive 𝑝-summing operators on 𝐿_ {𝑝}-spaces

O Blasco - Proceedings of the American Mathematical Society, 1987 - ams.org
It is shown that for any Banach space $ B $ every positive $ p $-summing operator from
${L^{p'}}(\mu) $ in $ B $, $1/p+ 1/p'= 1$, is also cone absolutely summing. We also prove …

Positive p-summing operators and disjoint p-summing operators

D Chen, A Belacel, JA Chávez-Domínguez - Positivity, 2021 - Springer
In the present paper, we introduce a new concept of positive p-majorizing operators as a
dual notion of positive p-summing operators and generalize the concept of majorizing …
