### (locally) symmetric spaces where every conformal transformation is an isometry

By an argument using Liouville's theorem for conformal maps Conformal automorphism of $H^n$ it can be shown that every conformal automorphism of a hyperbolic manifold is an isometry. Are there any ...

### Some confusion about Riemannian symmetric space

Recently I'm learning some basic theories about symmetric spaces from "Differential geometry, Lie groups, and symmetric space" written by Sigurdur Helgason, and I have some confusion. I Hope ...

### Computation of the LES of homotopy groups associated with compact symmetric spaces

I am looking for an efficient way to compute the homotopy groups, as well as morphisms between them, of certain matrix groups and compact symmetric spaces. To be specific, I want to determine the long ...

### Symmetrization map over the polynomial ring of a vector space.

Let $V$ be a finite-dimensional complex vector space. Is the morphism \begin{gather*} \mathrm{Sym}^{\bullet}(V \oplus V^*) \to D(V) \cong \frac{\mathrm{T}^{\bullet}(V\oplus V^*)}{I} \,, \\[0.5em] (v_1,...

### Maximum symmetry metric on Cayley Plane $F_4/Spin(9)$

The maximum symmetry metric on real projective space $\mathbb{RP}^n$ is the round metric. The maximum symmetry metric on complex projective space $\mathbb{CP}^n$ is the Fubini-Study metric. https:/...
