The symplectic structure of a toric conic transform
Abstract
Suppose that a compact -dimensional torus acts in a holomorphic and Hamiltonian manner on polarized complex -dimensional projective manifold , with nowhere vanishing moment map . Assuming that is transverse to the ray through a given weight , associated to these data there is a complex -dimensional polarized projective orbifold (referred to as the -th \textit{conic transform} of ). Namely, is a suitable quotient of the inverse image of the ray in the unit circle bundle of the polarization of . With the aim to clarify the geometric significance of this construction, we consider the special case where is toric, and show that is itself a K\"{a}hler toric obifold, whose moment polytope is obtained from the one of by a certain "transform", operation (depending on and ).
