||Erratum: The Duality Problem For The Class of AM-Compact Operators On Banach Lattices|
It is proved that if a positive operator
$S: E \rightarrow F$ is AM-compact whenever its adjoint
$S': F' \rightarrow E'$ is AM-compact, then either the
norm of F is order continuous or $E'$ is discrete.
This note corrects an error in the proof of Theorem 2.3 of
B. Aqzzouz, R. Nouira, and L. Zraoula, The duality problem for
the class of AM-compact operators on Banach lattices. Canad. Math. Bull.

||On the Existence of Asymptotic-$l_p$ Structures in Banach Spaces |
It is shown that if a Banach space is saturated with infinite
dimensional subspaces in which all ``special" $n$-tuples of
vectors are equivalent with constants independent of $n$-tuples and
of $n$, then the space contains asymptotic-$l_p$ subspaces
for some $1 \leq p \leq \infty$.
This extends a result by Figiel, Frankiewicz, Komorowski and
