论文摘要
在本说明中,我们将Jordan代数的有限前置性连接到其Tits-Kantor-Koecher代数的有限呈现性。通过此,我们完成了关于$ {\ Mathfrak {\ mathfrak {sl} _n(a)} $的有限余地的讨论,$ a $ a $ a $ a $ a $ a $ a $ a $ a $ a $ k $ - algebra,并回答了Shestakov-Zelmanov提出的问题。
In this note we connect finite presentability of a Jordan algebra to finite presentability of its Tits-Kantor-Koecher algebra. Through this we complete our discussion of finite presentability of universal central extensions of ${\mathfrak{sl}_n(A)}$, $A$ a $k$-algebra, initiated in our previous paper, and answer a question raised by Shestakov-Zelmanov in the positive.
