v-numbers of symbolic-ordinary discrepancy modules
Abstract
In this paper, we study the v-number of the symbolic-ordinary discrepancy modules Mt(I) = I(t) / It over standard graded Noetherian rings. We show that this coincides with the v-number of It at embedded primes. Moreover, under mild assumptions on I, we show that the v-number of Nt(I) = I(t) / I(t+1) is the same as the v-number of I(t+1). Furthermore, we provide combinatorial formulas for these v-numbers when t = 2, 3 and I is the edge ideal of a graph. Consequently, we classify all graphs for which v(I2) = v(I(2)).

AB - In this paper, we study the v-number of the symbolic-ordinary discrepancy modules M_t(I) = I^(t) / I^t over standard graded Noetherian rings. We show that this coincides with the v-number of I^t at embedded primes. Moreover, under mild assumptions on I, we show that the v-number of N_t(I) = I^(t) / I^(t+1) is the same as the v-number of I^(t+1). Furthermore, we provide combinatorial formulas for these v-numbers when t = 2, 3 and I is the edge ideal of a graph. Consequently, we classify all graphs for which v(I^2) = v(I^(2)).
