This book is dedicated to the memory of Florentin Smarandache, who listed many new and unsolved problems in number theory.
The results of this paper are concerned with the multi-covering radius, a generalization of covering radius, of Rank Distance (RD) codes. This leads to greater understanding of RD codes and their distance properties. Results on multi-covering radii of RD codes under various constructions are given by varying the parameters. Some bounds are established. A… (More)
