Abstract
We study some problems from various aspects of convexity, concerning shadow systems. Namely, we extend an old result of Rogers and Shephard, we provide a new simple proof to a result of Reisner, and we study a question related to Geometric Tomography, providing a characterization of central symmetry for convex bodies.
