Then substituting the expression for h in this formula and using Eq. Dynamics in Spaces of Constant Curvature. Generalized Bertrand Theorem We describe two approaches to the generalization of the Newtonian potential to the case of curved spaces, examining the example of spaces of constant curvature. Along with constants, there are only the following spherical-symmetric solutions of the Laplace equation in the n-dimensional Euclidean space with accuracy up to multiplication by a constant: Read e-book online Integrable problems of celestial mechanics in spaces of PDF.

Discussed are certain strange properties of the Galilei group, connected first of all with the property of mechanical energy-momentum covector to be an affine object, rather than the linear one. Its affine transformation rule is interesting in itself and dependent on the particle mass. On the quantum level this means obviously that we deal with the projective unitary representation of the group rather than with the usual representation. The status of mass is completely different than in relativistic theory, where it is a continuous eigenvalue of the Casimir invariant.

In Galilei framework it is a parameter characterizing the factor of the projective representation, in the sense of V. Galilei group, affine transformation, particle mass, projective unitary representation, Weyl-Wigner-Moyal-Ville formalism. Discussed are geometric structures underlying analytical mechanics of systems of affine bodies. Presented is detailed algebraic and geometric analysis of concepts like mutual deformation tensors and their invariants. Problems of affine invariance and of its interplay with the usual Euclidean invariance are reviewed.

This analysis was motivated by mechanics of affine homogeneously deformable bodies, nevertheless, it is also relevant for the theory of unconstrained continua and discrete media. Postulated are some models where the dynamics of elastic vibrations is encoded not only in potential energy sometimes even not at all but also sometimes first of all in appropriately chosen models of kinetic energy metric tensor on the configuration space , like in Maupertuis principle.

Physically, the models may be applied in structured discrete media, molecular crystals, fullerens, and even in description of astrophysical objects. Continuous limit of our affine-multibody theory is expected to provide a new class of micromorphic media. Systems of affine bodies, mutual deformation tensors, affine and Euclidean invariance, structured media, elastic vibrations, geometric structures. The proposed scheme is applied in two different contexts.

Firstly, the purely group-algebraic framework is applied to the system of angular momenta of arbitrary origin, e. Secondly, the other promising area of applications is Schroedinger quantum mechanics of rigid body with its often rather unexpected and very interesting features. Even within this Schroedinger framework the algebras of operators related to group algebras are a very useful tool.

They are related in an interesting way to geometry of the coadjoint orbits of SU 2. Systems of angular momenta, models with symmetries, quantum dynamics, spin systems, Schroedinger quantum mechanics, quasiclassical limit. In Part I of this series we have presented the general ideas of applying group-algebraic methods for describing quantum systems. Below we explicitly make use of the Lie group structure. Relying on differential geometry one is able to introduce explicitly representation of important physical quantities and to formulate the general ideas of quasiclassical representation and classical analogy.

In two previous parts we have discussed the methods of group algebras in formulation of quantum mechanics and certain quasiclassical problems. Below we specify to the special case of the group SU 2 and its quotient SO 3,R , and discuss just our main subject in this series, i. To be more precise, this is the purely SU 2 -treatment, so formally this might also apply to isospin. Systems of angular momenta, models with symmetries, quantum dynamics, quasiclassical isospin problems. Discussed is the structure of classical and quantum excitations of internal degrees of freedom of multiparticle objects like molecules, fullerens, atomic nuclei, etc.

Basing on some invariance properties under the action of isometric and affine transformations we reviewed some new models of the mutual interaction between rotational and deformative degrees of freedom. Our methodology and some results may be useful in the theory of Raman scattering and nuclear radiation. Internal degrees of freedom, isometric and affine invariance, classical and quantum excitations, multiparticle objects, Raman scattering, nuclear radiation. Discussed is mechanics of objects with internal degrees of freedom in generally non- Euclidean spaces.

Geometric peculiarities of the model are investigated in detail. Discussed are also possible mechanical applications, e. Elaborated is a new method of analysis based on nonholonomic frames. We compare our results and methods with those of other authors working in nonlinear dynamics. Simple examples are presented. Discussed is the quantized version of the classical description of collective and internal affine modes as developed in Part I. Some possible applications in nuclear physics and other quantum many-body problems are suggested. Elementary Topics -- 1. Domains with Smooth Boundaries -- 2.
