The Unique Path Lifting for Noncommutative Covering Projections
This article contains a noncommutative generalization of the topological path
lifting problem. Noncommutative geometry has no paths and even points. However
there are paths of *-automorphisms. It is proven that paths of *-automorphisms
comply with unique path lifting.Comment: 11 pages, 12 references. arXiv admin note: substantial text overlap

Noncommutative Generalization of Wilson Lines
A classical Wilson line is a cooresponedce between closed paths and elemets
of a gauge group. However the noncommutative geometry does not have closed
paths. But noncommutative geometry have good generalizations of both: the
covering projection, and the group of covering transformations. These notions
are used for a construction of noncommutative Wilson lines. Wilson lines can
also be constructed as global pure gauge fields on the universal covering
space. The noncommutative analog of this construction is also developed.Comment: 13 pages, 16 reference
