设$F$ 为域, $n\geq 3$, $\bf{N}$$(n,\mathbb{F})$ 为域$\mathbb{F}$ 上所有$n\times n$ 阶严格上三角矩阵构成的严格上三角矩阵李代数, 其李运算为$[x,y]=xy-yx$. $\bf{N}$$(n, \mathbb{F})$ 上一线性映射$\varphi$ 称为积零导子,如果由$[x,y]=0, x,y\in \bf{N}$$(n,\mathbb{F})$,总可推出 $[\varphi(x), y]+[x,\varphi(y)]=0$. 本文证明 $\bf{N}$$(n,\mathbb{F})$上一线性映射 $\varphi$ 为积零导子当且仅当 $\varphi$ 为$\bf{N}$$(n,\mathbb{F})$ 上内导子, 对角线导子, 极端导子, 中心导子和标量乘法的和. 相似文献

设T是定义在交换环上R的三角代数,φ:T×T→T是定义在T上的任意Jordan双导子.受[Comm.Algebra,2017,45(4):1741-1756]和[Linear Algebra Appl.,2009,431(9):1587-1602]研究的启发,本文致力研究φ的结构形式.我们指出在适当条件下Jordan双导子φ可以分解成内双导子和extremal双导子之和,推广了本方向现有成果.本文结果可直接应用于分块上三角矩阵代数和Hilbert空间定义的套代数. 相似文献

For a triangular algebra 𝒜 and an automorphism σ of 𝒜, we describe linear maps F,G:𝒜→𝒜 satisfying F(x)y+σ(x)G(y) = 0 whenever x,y∈𝒜 are such that xy = 0. In particular, when 𝒜 is a zero product determined triangular algebra, maps F and G satisfying the above condition are generalized skew derivations of the form F(x) = F(1)x+D(x) and G(x) = σ(x)G(1)+D(x) for all x∈𝒜, where D:𝒜→𝒜 is a skew derivation. When 𝒜 is not zero product determined, we show that there are also nonstandard solutions for maps F and G. 相似文献

Let (K,d) be a non-empty, compact metric space and α∈]0,1[. Let A be either lipα(K) or Lipα(K) and let B be a commutative unital Banach algebra. We show that every continuous linear map T:A→B with the property that T(f)T(g)=0 whenever f,g∈A are such that fg=0 is of the form T=wΦ for some invertible element w in B and some continuous epimorphism Φ:A→B. 相似文献

It is shown that a radical square zero algebra is wild, if and only if it is of Corner’s type, and it is strictly wild if
and only if it is Endo-wild. This gives a negative answer to a problem posed by Simson. 相似文献

In this article, we study the structure of zeroes of power series with Clifford algebra‐valued coefficients. Especially, if it has paravector‐valued coefficients, we obtain some sufficient and necessary conditions of power series that have zeroes, as well as a method to compute the zeroes if exist.

In this article, we study an important subalgebra of the tensor product partition algebra P k (x)? P k (y), denoted by P k (x, y) and called “Class Partition Algebra.” We show that the algebra P k (n, m) is the centralizer algebra of the wreath product S m ? S n . Furthermore, the algebra P k (x, y) and the tensor product partition algebra P k (x)? P k (y) are subalgebras of the G-colored partition algebra P k (x;G) and G-vertex colored partition algebra P k (x, G) respectively, for every group G with |G|=y ≥ 2k. 相似文献
