Ludvig Faddeev

In February 2017 Ludwig Dmitrievich Faddeev, one of the greatest modern math-ematicians and theoretical physicists, passed away. Faddeev’s death is a heavy loss to Russian and international science. His work has largely reshaped modern math-ematical physics, to the development of which he devoted his life. Many of his results have become classical, belonging to the gold reserve of pure mathematics, and at the same time playing a decisive role in the development of the most impor-tant areas of theoretical physics.
