关于两步幂零李代数皮质的注记

Note on the cortex of two-step nilpotent Lie algebras

Bechir Dali

摘要:

本文构造了一类$4d$维两步幂零李代数$(\frak g_d)_{d\geq 2}$,使得每个$\frak g_d$的对偶的皮质是一个射影代数集.更准确地说,我们表明,皮质的每个双$\frak g_d^*$的$\frak g_d$是零集齐次多项式的$d$。这个例子是一个推广的“不可约表示的局部紧群,不能从单位表示Hausdorff分离”由“{ \sc M.E.B. Bekka和E. Kaniuth}"。

英文摘要:

In this paper, we construct an example of a family of $4d$-dimensional two-step nilpotent Lie algebras $(\frak g_d)_{d\geq 2}$ so that the cortex of the dual of each $\frak g_d$ is a projective algebraic set. More precisely, we show that the cortex of each dual $\frak g_d^*$ of $\frak g_d$ is the zero set of a homogeneous polynomial of degree $d$. This example is a generalization of one given in "Irreducible representations of locally compact groups that cannot be Hausdorff separated from the identity representation" by "{\sc M.E.B. Bekka, and E. Kaniuth}".
