Formation and Evolution of Structure in Loop Cosmology — •Martin Bojowald — Institute for Gravitational Physics and Geometry, The Pennsylvania State University, University Park, PA 16802, USA

Inhomogeneous cosmological perturbation equations are introduced, taking into account corrections from microscopic scales of loop quantum gravity. This provides a framework for calculating the evolution of modes in structure formation scenarios related to inflationary or bouncing models. Specific applications to be presented are corrections to the Newton potential and to the evolution of large scale modes which imply non-conservation of curvature perturbations possibly noticeable in a running spectral index.
