Karl Mikhailovich Peterson
Karl Mikhailovich Peterson was a Russian mathematician, known by an earlier formulation of the Gauss–Codazzi equations.
Life and work
Peterson was born in a peasant family. He studied at the Gymnasium of Riga and, after, at the Imperial University of Dorpat under Ferdinand Minding.Nothing of his life is known about the ten years after his graduation. In unknown date he went to Moscow where he taught in the German Gymnasium Peter and Paul of this city from 1865. Peterson never had an academic position at university level, but he was one of the founders of the Moscow Mathematical Society with Nikolai Brashman and August Davidov. Peterson was a notable collaborator in the journal of the Society and he is considered the founder of the Moscow school of geometry.
Peterson gave, in his graduation dissertation, an earliest formulation of the fundamental equations of the surface theory, now usually known as Gauss–Codazzi equations, sometimes Peterson–Codazzi equations.
During his time in Moscow, Peterson published some important papers about differential geometry. In 1879, the university of Odessa awarded him an honorary degree.
