Dynamics on Differential One-Forms proposes a unifying precept for mathematical versions of dynamic structures. In "Thermodynamics on One-Forms (chapter I)", the long-standing challenge of deriving irreversibility in thermodynamics from reversibility in Hamiltonian mechanics, is solved. Differential geometric research indicates thermodynamics and Hamiltonian mechanics are either irreversible on consultant prolonged section areas. "Dynamics on Differential One-Forms (II)" generalizes (I) to Hamiltonian mechanics, geometric optics, thermodynamics, black holes, electromagnetic fields and string fields. Mathematical types for those structures are published as representations of a unifying precept; particularly, description of a dynamic method with a attribute differential one-form on an odd-dimensional differentiable manifold leads, via research with external calculus, to a collection of differential equations and a tangent vector defining method differences. Relationships among types utilizing external calculus and standard calculus suggest a technical definition of dynamic equilibrium. "Global research of Composite debris (III)" makes use of differential topology to boost the idea of huge vibration-rotation interactions for composite debris. an international classical Hamiltonian and corresponding quantum Hamiltonian operator are derived, then utilized to the molecular vibration-rotation problem."Characteristic Electromagnetic and Yang-Mills Gauge (IV)" makes use of differential geometry to take away many of the arbitrariness within the gauge, and indicates how gauge services for electromagnetic and Yang-Mills fields persist with a similar differential equation.

However, df is already a scalar, whereas df must be contracted with a tangent vector v to become a scalar. The operation of contraction, denoted by df (v ), thus removes the arbitrariness in the direction of the displacement, where this direction is the same as that of the tangent vector v (tangent vectors and the exterior derivative operator are denoted by italicized boldface symbols and a boldface d, respectively). In this setting, consider an n-dimensional differentiable manifold M with n local coordinates x k.

17) is given by utilizing familiar definitions of characteristic function S . Then, as a prelude to directly applicable forms of these latter equations, a discussion of the difference in the manner in which physical processes are perceived theoretically through differential geometry and the manner in which they are perceived 18 Dynamics on Differential One-Forms empirically through measurements, is presented. Finally, a discussion is given of the use of these equations. The characteristic function for a simple process in Hamiltonian dynamics is the usual expression for the Hamiltonian as the sum of kinetic and potential energy functions.

If x k and bk are to describe mappings of the temporal coordinate onto the direction of the system phase flow, then x k and bk must be functions of x 0 alone, and vector ξ , where ξ = dbk dx k ∂ ∂ (∂ ) + (∂∂/∂∂x k ) + (∂∂/∂∂x /∂ b k dx o dx o o ) (4) must satisfy at each point (bk , x k , x 0 ) of the transformation, the equation dω ( ξ , η ) = 0 (5) 33 Tr o y L . S t o r y for arbitrary tangent vector η at each point. (4) is removed. (6), is called the vortex vector. (6)) passing through points of a closed curve called the vortex tube.
