The NASA Kepler spacecraft has detected 170 candidate multi-planet systems in the rst two quarters of data released in February 2011 by Borucki et al. (2011). These systems comprise 115 double candidate systems, 45 triple candidate sys- tems, and 10 systems with 4 or more candidate planets. The architecture and dynamics of these systems were discussed by Lissauer et al. (2011), and a comparison of candidates in single- and multi-planet systems was presented by Latham et al. (2011). Proceeding from planetary candidate systems to con rmed and validated multi-planet systems is a di cult process, as most of these systems orbit stars too faint to obtain extremely precise (1ms-1) radial velocity con rmation. Here, we discuss in detail the use of transit timing vari- ations (cf. e.g. Holman et al., 2010) to con rm planets near a mean motion resonance. We also discuss extensions to the BLENDER validation (Torres et al., 2004, 2011; Fressin et al., 2011) to validate planets in multi-planet systems. Kepler was competitively selected as the tenth Discovery mission. Funding for the Kepler Mis- sion is provided by NASA's Science Mission Direc- torate. We are deeply grateful for the very hard work of the entire Kepler team.
