Spinors, Nonlinear Connections, and Nearly Autoparallel Maps of Generalized Finsler Spaces

Abstract

We review the geometric setting of the field theory with locally anisotropic interactions. The concept of locally anisotropic space is introduced as a general one for various type of extensions of Lagrange and Finsler geometry and higher dimension (Kaluza--Klein type) spaces. The problem of definition of spinors on generalized Finsler spaces is solved in the framework of the geometry of Clifford bundles provided with compatible nonlinear and distinguished connections and metric structures. We construct the spinor differential geometry of locally anisotropic spaces and discuss some related issues connected with the geometric aspects of locally anisotropc interactions for gravitational, gauge, spinor, Dirac spinor and Proca fields. Motion equations in generalized Finsler spaces, of the mentioned type of fields, are defined in a geometric manner by using bundles of linear and affine frames locally adapted to the nonlinear connection structure. The nearly autoparallel maps are introduced as maps with deformation of connections extending the class of geodesic and conformal transforms. Using this approach we propose two variants of solution of the problem of definition of conservation laws on locally anisotropic spaces. 1991 Mathematics Subject Classification: 53A50, 53B15, 53B40, 53B50, 53C05, 70D10, 81D27, 81E13, 81E20, 83C40, 83C47, 83D05, 83E15 Key words and phrases: Spinors, nonlinear connections, generalized Lagrange and Finsler spaces, locally anisotropic fields, nearly autoparallel maps, conservation laws.
