Abstract

Let S=k[x11,,x1b1,,xn1,,xnbn]S = k[x_{11}, \cdots, x_{1b_1}, \cdots, x_{n1}, \cdots, x_{nb_n}] be a polynomial ring in m=b1++bnm = b_1 + \cdots + b_n variables over a field kk. For all jj, 1jn1\le j \le n, let PjP_j be the prime ideal generated by variables {xj1,,xjbj}\{x_{j1}, \cdots, x_{jb_j}\} and let In,t=1j1<<jtnPj1PjtI_{n, t} = \sum_{1\le j_1< \cdots <j_t\le n} P_{j_1}\ldots P_{j_t} be the transversal monomial ideal of degree tt on P1,,PnP_1, \cdots, P_n. We explicitly construct a canonical polytopal Zt\mathbb{Z}^t-graded minimal free resolution for the ideal In,tI_{n, t} by means of suitable gluing of polytopes.
