    Arithmetical rank of binomial ideals
    (Birkhaeuser Science, 2017) Katsabekis, A.
    In this paper, we investigate the arithmetical rank of a binomial ideal J. We provide lower bounds for the binomial arithmetical rank and the J-complete arithmetical rank of J. Special attention is paid to the case where J is the binomial edge ideal of a graph. We compute the arithmetical rank of such an ideal in various cases. © 2017, Springer International Publishing AG.
