Yuri M. Grigoriev

Dr. Sci. (Physics and Mathematics), Associate professor, Head of the Physics and Technology Department, North-Eastern Federal University (Yakutsk, Russia)

Research interests: quaternion analysis, electromagnetic compatibility, elasticity theory, mathematical modeling in natural scienсes. Dr. Yuri Grigoriev studied regular functions of a quaternion variable and their applications in mechanics. He has concentrated on electromagnetic compatibility in permafrost conditions, mathematical modeling of diamond processing, and developed a new method of disintegration and preliminary enrichment of kimberlites.
