Title: Supercongruences for rigid hypergeometric Calabi-Yau threefolds

Abstract: We give two proofs of the supercongruences for the fourteen rigid hypergeometric Calabi-Yau threefolds defined over Q. The existence of such supercongruences was conjectured (based on numerical evidence) by F. Rodriguez-Villegas in 2003.
