Theory of Differential Equations: Pfaff equations and applications
The problem that became known as Pfaff’s problem had its origins in the theory of first order partial differential equations, which as a general theory began with Euler, Monge and Lagrange. Nowadays the problem of Pfaff is characterized more specifically as the problem of determining for a given Pfaffian equation ω = 0 in n variables the maximal dimension d of its integral manifolds. This problem is a keystone in all the modern integrability theories in classical mechanics: Euler-Jacoby, Liouville, Lie, Frobenius, Darboux, Cartan and Yang-Baxter theories. We plan to discuss the classical Pfaff theory and its modern applications in Hamiltonian and nonholonomic mechanics.
