Seidel Representation for Symplectic Orbifolds

Let $(\text{X},\omega )$ be a compact symplectic orbifold. We define $\pi_1(Ham(\X, \omega))$, the fundamental group of the 2-group of Hamiltonian diffeomorphisms of $(\text{X},\omega )$, and construct a group homomorphism from $\pi_1(Ham(\X, \omega))$tothegroup$QH_{orb}^*(\X,\Lambda)^{\times}$ of multiplicatively invertible elements in the orbifold quantum cohomology ring of $(\text{X},\omega )$. This extends the Seidel representation ([Se], [M]) to symplectic orbifolds.
