Recovering $U(n)$-invariant toric Kähler metrics on $\mathbb{C}\mathbb{P}^n$ from the torus equivariant spectrum
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 eigenvalues of the Laplacian together with weights of the torus representation on the eigenspaces.
