Jerzy
Julian Konderak
was born
in Krakow (Poland) in 1956, graduated in mathematics in 1980 and got
his Ph.D.
from the Jagiellonian University in 1986.
He worked at Institute of Mathematics from 1986 to 1989. At that
time
his mathematical interests concentrated on geometrical objects and
differential
geometry of higher order.
In
1989
he got a scholarship to The Abdus Salam
International Centre for Theoretical Physics, Trieste, Italy, where he
met
James Eells. He got interested in
harmonic maps. It was a long lasting fascination and he dedicated a lot
of
effort to the study of the theory. He
settled in Italy, married Luigia di Terlizzi and started to work at
Università
degli
Studi di Bari, not long ago was named a
professor at that university.
Jerzy had a
very
open and inquisitive mind, always willing to learn more, meet new
people, get
to know new countries. His research in mathematics was not confined to
one
narrow topic, he read widely, had a lot of fine ideas, but
unfortunately
published few papers, leaving many unfinished, just sketched. He was
very
attentive to details, even minor, paying particular attention to
examples. And
indeed his papers contain many fine examples.
It is
very sad that
finally obtaining the stability of a professorship, reaching research
maturity,
he passed away leaving a long queue of uncompleted publications and
warm
memories among his numerous friends and colleagues.
