HOMAGE IN ESCIM25
ESCIM 2025 was dedicated to the memory of Professor Alexander Šostak, an outstanding researcher and a beloved member of the ESCIM community. His remarkable contributions to mathematics and theoretical computer science have shaped the field and continue to inspire generations of researchers.
Alexander was not only a brilliant academic, but also a warm and generous person. A regular participant in many editions of ESCIM. His legacy bridges rigorous theoretical foundations with forward-looking applications — a testament to a truly remarkable academic journey.
A special session od ESCIM25 was dedicated to Professor Alexander Šostak, honoring his outstanding contributions to mathematics and theoretical computer science.
Prof. Jesús Medina from the University of Cádiz, on behalf of the ESCIM25 organization, presented a commemorative certificate «In Loving Memory of Alexander Šostak» to his family.
The certificate was delivered through Prof. Olga Grigorenko from the University of Latvia, a close collaborator and team member of Prof. Šostak.
