Professor Yeshkeyev’s Life in Science and Logic: Celebrating the Scholar’s 70th Anniversary

Abstract

In the age of digitalisation and rapid technological progress, it is easy to forget that every computer program, every algorithm, and the very structure of our thinking are founded on mathematical logic. In this abstract yet vitally important field, Kazakhstan has its own recognised authority. In May 2026, Aibat Rafhatovich Yeshkeyev marks his 70th birthday. He is a Doctor of Physical and Mathematical Sciences, Professor, and Professor-Researcher at the Karaganda National Research University named after àcademician Ye.A. Buketov, a man whose work in model theory has built a bridge between Kazakhstani science and the international academic community.
