摘要

我们定义了在完整语义（不一定是交换语义）上有存储的有理加权树语言类，并重复了有存储的加权正则树语法对它的描述。此外，我们还给出了另一种证明，即有存储空间的有理加权树语言类在有理运算（即顶协、标量乘法、和、树协和和克莱因星）下是封闭的，其中后两个封闭结果要求存储空间有重置指令。

Rational weighted tree languages with storage

We define the class of rational weighted tree languages with storage over complete, not necessarily commutative, semirings and we repeat its characterization by weighted regular tree grammars with storage. Moreover, we show an alternative proof of the fact that the class of rational weighted tree languages with storage is closed under the rational operations, i.e., top-concatenation, scalar multiplication, sum, tree concatenation, and Kleene-star, where the latter two closure results require that the storage has a reset instruction.
