  We develop formalism for computing the kinetic terms of 4d fields in string
compactifications, particularly with warping. With the help of the Hamiltonian
approach, we identify a gauge dependent inner product on the compactification
manifold which depends on the warp factor. It is shown that kinetic terms are
associated to the minimum value of the inner product over each gauge orbit. We
work out the kinetic term for the complex modulus of a deformed conifold with
flux, i.e. the Klebanov-Strassler solution embedded in a compact Calabi-Yau
manifold. Earlier results of a power-like divergence are confirmed
qualitatively (the kinetic term does contain the main effect of warping) but
not quantitatively (the correct results differ by an order one coefficient).
