A characterization of covering equivalence | | Hao Pan

27 Sep 2004 | | Subject: | Number Theory; Combinatorics MSC-class: 11B25; 11A07; 11B75 | math.NT math.CO | | Abstract: | Let A={a_s(mod n_s)}_{s=1}^k and B={b_t(mod m_t)}_{t=1}^l be two systems of residue classes. If |{1le sle k: x=a_s (mod n_s)}| and |{1le tle l: x=b_t (mod m_t)}| are equal for all integers x, then A and B are said to be covering equivalent. In this paper we characterize the covering equivalence in a simple and new way. Using the characterization we partially confirm a conjecture of R. L. Graham and K. O’Bryant. | | Source: | arXiv, math.NT/0409521 | | Services: | Forum | Review | PDF | Favorites | |
