Abstract: Real projective structures are given as projectively flat structures on manifolds or orbifolds. Hyperbolic structures form good examples. Deforming a hyperbolic structure into a family of real projective structures might be interesting from some perspectives. We will try to find complete projective invariants to deform projective 3-orbifolds with triangulations and obtain some deformations of reflection groups based on tetrahedra, pyramids, octahedra, and so on. (We will give some introduction to this area of research in the talk.)
