In 1818 he introduced his barycentric calculus, and later influenced projective geometry with his namesake net.
This man's namesake tetrahedra are two tetrahedra that mutually circumscribe and inscribe each other, and his namesake "mu function" gives a measure of the number of distinct primes in square-free integers. A variation of this man's most famous mathematical contribution provides an example of a non-trivial vector bundle over the circle. In 1818 he introduced his barycentric calculus, and later influenced projective geometry with his namesake net. Formulator of the "four-color" problem, FTP, who was this German mathematician best known for his one-sided strip?
