Volume 69 / 2021

Daria Holik, Marek Karaś Bulletin Polish Acad. Sci. Math. 69 (2021), 11-20 MSC: Primary 14R15, 13N15; Secondary 17B63. DOI: 10.4064/ba210123-12-7 Published online: 29 July 2021

Abstract

Let k be a field of characteristic zero. In this note, for given linear forms L_1,L_2\in k[x_1,\ldots ,x_n] and given r,s\in \mathbb {N}_+=\mathbb {N}\setminus \{ 0\}, we consider the equation [L_1^r,P_1]=[P_2,L_2^s] with unknowns P_1,P_2\in k[x_1,\ldots ,x_n], and give a complete description of the set of all solutions of such an equation. Equivalently, the above equation can be written as an equation for differential forms: d(L_1^r)\wedge dP_1 = dP_2\wedge d(L_2^s).
