WebSep 15, 2024 · In this paper, we prove new bounds for both the degrees in the Nullstellensatz and the Noether exponent of an ideal in the sparse setting. Our work is in the vein of [10] and [17], in the sense that we consider arbitrary sparse systems (that is, no genericity assumptions are made).
