Recovering $U(n)$-invariant toric Kähler metrics on $\mathbb{C}{\mathbb{P}}^n$ from the torus equivariant spectrum

Tomás A. Reis, Rosa Sena-Dias

In this note we prove that toric Kähler metrics on complex projective space which are also $U(n)$-invariant are determined by their equivariant spectrum i.e. the list of eigenvalue…
