On the single valuedness of Hamilton-Jacobi operators
Nonlinear Analysis: Theory, Methods & Applications, 1986We study some properties of Dini subdifferentials and their relations with upper contingent derivative of a function. The results are applied to the problem of single-valuedness of Hamilton-Jacobi operators.

Hamilton Type Gradient Estimate for the Sub-Elliptic Operators
Potential Analysis, 2014Let \(M \) be a smooth, connected, finite-dimensional manifold endowed with a smooth measure and a symmetric, second-order, locally sub-elliptic and negative diffusion operator \(L \) satisfying \(L 1=0 \) as in [\textit{F. Baudoin} et al., Math. Ann. 358, No. 3--4, 833--860 (2014; Zbl 1287.53025)].

Hamilton operators and homothetic motions inR 3
Applied Mathematics and Mechanics (English Edition), 2004Quaternion is a division ring. It is shown that planes passing through the origin can be made a field with the quaternion product in R3. The Hamiltonian operators help us define the homothetic motions on these planes. New characterizations for these motions are investigated.

Hamilton operators and dual-number-quaternions in spatial kinematics
Mechanism and Machine Theory, 1987Abstract Dual-number-quaternions are used frequently in spatial screw motion of a rigid body. In this paper, two Hamilton operators are defined and the algebra of dual-number-quaterinions is developed using these operators. Properties of Hamilton operators are then used to find some mathematical expressions for screw motion of a line and a point. The

Self-adjoint Hamilton Operators
2003The time evolution of a classical mechanical system is governed by the Hamilton function. Similarly, the Hamilton operator determines the time evolution of a quantum mechanical system and this operator provides information about the total energy of the system in specific states.

ALMOST STABILITY OF HAMILTON'S EQUATIONS WITH QUASIPERIODIC OPERATOR COEFFICIENTS
Mathematics of the USSR-Sbornik, 1970This article studies a hamiltonian equation in Hilbert space which differs by only small quasiperiodic perturbations from equations with constant coefficients with several special properties. Necessary and sufficient conditions are obtained for strong formal stability of the hamiltonian equation with constant coefficients within some class of ...

Classical Analogs of Unitarily Equivalent Hamilton Operators
Foundations of Physics, 1998A unitary transformation replaces the given description of a quantum system by an equivalent one. It is observed, however, that not all members of a set of unitarily equivalent Hamilton operators are equally well suited for identifying the corresponding classical systems. A criterion is proposed for recognizing the privileged representatives of the set.

Integrated Operations... Hamilton Farm Bureau Cooperative
1959Excerpts from the report: This is the third in a series of case studies by Farmer Cooperative Service on the integrated operations of cooperatives. It is the first such study, however, that deals specifically with the integration process as it has been developed by a local association.
