Sandwich operators and Einstein deformations of compact symmetric spaces related to Jordan algebras

Stuart James Hall, Paul Schwahn, Uwe Semmelmann

We study the deformability of the symmetric Einstein metrics on the spaces $\mathrm{SU}(n)/\mathrm{SO}(n)$ and $\mathrm{SU}(2n)/\mathrm{Sp}(n)$, thereby concluding the problem to s…
