Images of Linear Derivations and Linear E-derivations of K[x 1 ,x 2 ,x 3 ]

Haifeng Tian, Xiankun Du, Hongyu Jia

Let K be a field of characteristic zero. We prove that images of a linear K-derivation and a linear K-E-derivation of the ring K[x 1 ,x 2 ,x 3 ] of polynomial in three variables ov…

Commuting maps on certain incidence algebras

Hongyu Jia, Zhankui Xiao

Let $R$ be a $2$ -torsion free commutative ring with unity, $X$ a locally finite pre-ordered set and $I (X, R)$ the incidence algebra of $X$ over $R$ . If…
