We extend Shelukhin's proof of the homology version of the Hofer-Zehnder conjecture to weighted projective spaces, which are symplectic orbifolds. In particular, we show that if the number of fixed points, counted with their isotropy order as multiplicity, of a non-degenerate Hamiltonian diffeomorphism in such a space is larger than the minimum possible value, then there are infinitely many periodic points.
We prove an extension of the homology version of the Hofer-Zehnder conjecture proved by Shelukhin to the weighted projective spaces which are symplectic orbifolds. In particular, we prove that if the number of fixed points counted with their isotropy order as multiplicity of a non-degenerate Hamiltonian diffeomorphism of such a space is larger than the minimum number possible, then there are infinitely many periodic points.
