Özet

In this work, the cardinality of the minimal R-covers of finite rings with respect to the RI-metric is established. By generalizing the result in Nakaoka and dos Santos (2010) 111, the minimal cardinalities of 0-short coverings of finite chain rings are calculated. The connection between R-short coverings of rings with respect to the RT-metric and the 0-short coverings of rings is demonstrated, and with the help of this connection, the problem of finding the minimal cardinalities of R-short coverings of finite chain rings is solved.
