Alexander P. Yefremov is a Russian physicist, vice rector at Peoples' Friendship University of Russia and director of its Institute of Gravitation and Cosmology.

He has worked at the Peoples' Friendship University of Russia (PFUR) since 1977, among others as its vice rector and head of its physics division.^[1][2]

Yefremov is known for his work in theoretical physics, among others, for his fundamental work on the role of quaternion geometry space in quantum mechanics and field theory.

Publications[edit]

Yefremov has authored more than 70 scientific publications in collections and journals.^[2]
