Query: Daugavet- and Delta-points in absolute sums of Banach spaces   A Daugavet-point (resp.~$\Delta$-point) of a Banach space is a norm one
element $x$ for which every point in the unit ball (resp.~element $x$ itself)
is in the closed convex hull of unit ball elements that are almost at distance
2 from $x$. A Banach space has the well-known Daugavet property
(resp.~diametral local diameter 2 property) if and only if every norm one
element is a Daugavet-point (resp.~$\Delta$-point). This paper complements the
article "Delta- and Daugavet-points in Banach spaces" by T. A. Abrahamsen, R.
Haller, V. Lima, and K. Pirk, where the study of the existence of Daugavet- and
$\Delta$-points in absolute sums of Banach spaces was started.
