Abstract
The paper [2] opens a list of joint publications by George P.H. Styan
and Jerzy K. Baksalary. Even though Jerzy passed away prematurely
in 2005, the cooperation between George and the Baksalarys has continued up to the present days. It is now Jerzy’s son and the author
of the present talk who has a privilege and pleasure to work together
with George. So far the cooperation between George and the two Baksalarys resulted in 16 papers, including 9 joint papers by George and
Jerzy and 8 joint papers by George and Oskar. Thus, there is one joint
paper by George, Jerzy, and Oskar, namely [1]. In the talk several
comments on the joint publications by George and the Baksalarys will
be made.
