LF-代数表示与李群表示的连续性

Continuity of LF-algebra representations associated to representations of Lie groups

Helge Glockner

摘要:

设G是李群,E是局部凸拓扑G-模.若E是序列完备的,则E及其光滑向量空间是G上紧支撑光滑函数代数D(G)的模.然而,模乘法不需要是连续的。如果E是(或嵌入)Banach G-模的投射极限,则可以排除病理。此外,在这种情况下,解析向量空间是Gimperlein,Kroetz和Schlichtkrull引入的超衰减解析函数代数A(G)的模。证明了解析向量空间是拓扑A(G)-模,如果E是巴拿赫空间,或者更一般地,如果E上的每个连续模的可数集都有一个上界.当G是紧李代数时,也得到了同样的结论.讨论了D(G)和A(G)是否为拓扑代数的问题。

英文摘要:

Let G be a Lie group and E be a locally convex topological G-module. If E is sequentially complete, then E and its space of smooth vectors are modules for the algebra D(G) of compactly supported smooth functions on G. However, the module multiplication need not be continuous. The pathology can be ruled out if E is (or embeds into) a projective limit of Banach G-modules. Moreover, in this case the space of analytic vectors is a module for the algebra A(G) of superdecaying analytic functions introduced by Gimperlein, Kroetz and Schlichtkrull. We prove that the space of analytic vectors is a topological A(G)-module if E is a Banach space or, more generally, if every countable set of continuous seminorms on E has an upper bound. The same conclusion is obtained if G has a compact Lie algebra. The question of whether D(G) and A(G) are topological algebras is also addressed.
