    "abstract": "The quantum deformation $CP_q(N)$ of complex projective space is discussed.\nMany of the features present in the case of the quantum sphere can be extended.\nThe differential and integral calculus is studied and $CP_q(N)$ appears as a\nquantum K\\\"{a}hler manifold. The braiding of several copies of $CP_q(N)$ is\nintroduced and the anharmonic ratios of four collinear points are shown to be\ninvariant under quantum projective transformations. They provide the building\nblocks of all projective invariants. The Poisson limit is also described.",
