The Canonical Exact Sequence of Differential Modules for 0-Dimensional Schemes

Tran N. K. Linh, Le Ngoc Long

Given a 0-dimensional scheme $\X$ in $P_{K}^{n}$ over a perfect field $K$ , we examine the second differential power of its homogeneous vanishing ideal. This enables us to esta…

The Kähler Different of a Set of Points in $P^{m} \times P^{n}$

Tran N. K. Linh, Le N. Long, Nguyen T. Hoa +2

Given an ACM set $X$ of points in a multiprojective space $P^{m} \times P^{n}$ over a field of characteristic zero, we are interested in studying the Kähler di…

Hilbert Polynomials of Kähler Differential Modules for Fat Point Schemes

Martin Kreuzer, Tran N. K. Linh, Le Ngoc Long

Given a fat point scheme $W = m_{1} P_{1} + \dots + m_{s} P_{s}$ in the projective $n$ -space $P^{n}$ over a field $K$ of characteristic zero, the modules of Kähler differential $k…
