李群表示的解析因式分解

Analytic factorization of Lie group representations

Heiko Gimperlein, Bernhard Krötz, Christoph Lienau

摘要:

对Frechet空间E上实李群G的每一个适度增长表示,证明了解析向量空间E^ω的Dixon-Malliavin型分解定理.存在超指数递减解析函数A(G)的自然代数,使得E^ω = A(G)* E^ω.作为推论,我们得到了E^ω与G上Laplace-Beltrami算子的解析向量空间一致.

英文摘要:

For every moderate growth representation of a real Lie group G on a Frechet space E, we prove a factorization theorem of Dixmier--Malliavin type for the space of analytic vectors E^ω. There exists a natural algebra of superexponentially decreasing analytic functions A(G), such that E^ω = A(G) * E^ω. As a corollary we obtain that E^ωcoincides with the space of analytic vectors for the Laplace--Beltrami operator on G.
