IN your issue of January 29, Mr. Heaviside put forward a demonstration of Lagrange's equations of motion which appears invalid. As neither his interpretation of Newton nor his argument based thereon ...
The Lagrangian description of absolutely continnous curves of probability measures on the real line is analyzed. Whereas each such curve admits a Lagrangian description as a well-defined flow of its ...
Kinematics of nonholonomic systems; dynamics of nonholonomic systems, including d’Álembert principle, Euler-Lagrange equations; equations of motion of nonholonomic systems with Lagrangian multipliers; ...
We obtain a priori interior Hessian and gradient estimates for special Lagrangian equations with phase larger than a critical value in dimension three. Gradient estimates are also derived for critical ...
