We had first known about Yuriy Nikolayevich Pecherskiy
and his laboratory at the end of 1980-ies, when
we looked for an opportunity of post-graduate study.
One of our friends, who attended a school organized by
Yuriy Nikolayevich, was very impressed by the
interesting topics and enthusiastically recommended
us to get in contact with him.
After several phone conversations and a personal
meeting in Kishinev, we were invited to passing
the entrance exams for the post-graduate programme
at the Institute of Mathematics.
After almost 30 years, we can say with certainty
that this was a turning point in our academic
careers and lives.
In 1988, we have entered the post-graduate programme at the Institute of Mathematics and started our studies in the laboratory of Mathematical Cybernetics lead by Yuriy Nikolayevich. Our scientific advisor was Sergey Solovyov. Over the three years of our study, we always felt the sympathy, support, and assistance of Yuriy Nikolayevich. His advices were invaluable for us as young scholars and just young people. Apart from the purely academic support, he helped us in the search for applied research, which enabled us to successfully cope with the known problems of the transition period.
Unfortunately, the collapse of the USSR in the early 1990s that resulted in very difficult conditions for the academic science and threats to its survival forced us to leave Moldavia for the region of Moscow and, later, to accept the invitation to work in Germany at the National Centre for Mathematics and Data Processing (GMD), now the Fraunhofer Institute IAIS. These decisions were very hard for us. We are sincerely grateful to Yuriy Nikolayevich for his support and understanding during this difficult period.
We remember our last conversation before our departure from Kishinev. Yuriy Nikolayevich was very hopeful that the situation would change for the better and we would be able to come back. Unfortunately, our hopes did not come to reality. We often recall this conversation and, as before, feel deep gratitude to Yuriy Nikolayevich for his warmth and paternal care.
Yuriy Nikolayevich specially came to Moscow in 1993 to support us at the defence of the candidate thesis of Natalia Andrienko at the Moscow State University. Sadly, that was our last meeting.
