In 1912, attempting to solve the four color problem, Birkhoff introduced the chromatic polynomial. Even though this line of attack did not prove fruitful, the polynomial itself became an important object of study in algebraic graph theory. In 1913, he proved Poincaré's "Last Geometric Theorem," a special case of the three-body problem, a result that made him world-famous. In 1927, he published his Dynamical Systems. … WebSep 2, 2015 · In 1927, the American mathematician Birkhoffian [ 35] presented a new form integral variational principle and give a new equations of motion in his famous works.
