520 | |a Abstract Let M be a compact connected smooth pseudo-Riemannian manifold that admits a topologically transitive G-action by isometries, where %$G = G_1 \ldots G_l%$ is a connected semisimple Lie group without compact factors whose Lie algebra is %${\mathfrak {g}}= {\mathfrak {g}}_1 \oplus {\mathfrak {g}}_2 \oplus \cdots \oplus {\mathfrak {g}}_l%$. If %$m_0,n_0,n_0^i%$ are the dimensions of the maximal lightlike subspaces tangent to M, G, %$G_i%$, respectively, then we study G-actions that satisfy the condition %$m_0=n_0^1 + \cdots + n_0^{l}%$. This condition implies that the orbits are non-degenerate for the pseudo Riemannian metric on M and this allows us to consider the normal bundle to the orbits. Using the properties of the normal bundle to the G-orbits we obtain an isometric splitting of M by considering natural metrics on each %$G_i%$. | ||

If %$m_0,n_0,n_0^i%$ are the dimensions of the maximal lightlike subspaces tangent to M, G, %$G_i%$, respectively, then we study G-actions that satisfy the condition %$m_0=n_0^1 + \cdots + n_0^{l}%$. This condition implies that the orbits are non-degenerate for the pseudo Riemannian metric on M and this allows us to consider the normal bundle to the orbits. Using the properties of the normal bundle to the G-orbits we obtain an isometric splitting of M by considering natural metrics on each %$G_i%$.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Bi-invariant metric</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pseudo-Riemannian</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Semisimple Lie group</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Topologically transitive action</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Abhandlungen aus dem Mathematischen Seminar der Universität Hamburg</subfield><subfield code="d">Berlin [u.a.] : Springer, 1922</subfield><subfield code="g">91(2021), 2 vom: 07.

A geometric splitting theorem for actions of semisimple Lie groups |
abstract |
Abstract Let M be a compact connected smooth pseudo-Riemannian manifold that admits a topologically transitive G-action by isometries, where %$G = G_1 \ldots G_l%$ is a connected semisimple Lie group without compact factors whose Lie algebra is %${\mathfrak {g}}= {\mathfrak {g}}_1 \oplus {\mathfrak {g}}_2 \oplus \cdots \oplus {\mathfrak {g}}_l%$. If %$m_0,n_0,n_0^i%$ are the dimensions of the maximal lightlike subspaces tangent to M, G, %$G_i%$, respectively, then we study G-actions that satisfy the condition %$m_0=n_0^1 + \cdots + n_0^{l}%$. This condition implies that the orbits are non-degenerate for the pseudo Riemannian metric on M and this allows us to consider the normal bundle to the orbits. Using the properties of the normal bundle to the G-orbits we obtain an isometric splitting of M by considering natural metrics on each %$G_i%$. © The Author(s), under exclusive licence to Mathematisches Seminar der Universität Hamburg 2021 |
