摘要
设 k 是特征为零的域。如果 c1,c2∈k∖{0},s,t≥1 且 u≥0，那么可以证明 k[x, y] 的 k 衍 ∂x+xu(c1xtys+c2)∂y 和 ∂x+xu(c1xt+c2ys+1)∂y 是简单的。我们还给出了一个新的...
Let k be a field of characteristic zero. If c1,c2∈k∖{0},s,t≥1 and u≥0, then it is shown that the k-derivations ∂x+xu(c1xtys+c2)∂y and ∂x+xu(c1xt+c2ys+1)∂y of k[x, y] are simple. We also give a nece...
