Title: Cyclic unramified coverings of varieties.
Abstract: We will show how cyclic unramified coverings of algebraic
varieties can be constructed using units in the coordinate ring of the
variety, or torsion divisor classes. Converse of this will also be
discussed. We will show how topology of the variety influences such
covers.
