Popis:	We consider lifting of mod p representations to mod p^2 representations in the setting of representations of (i) finite groups; (ii) absolute Galois groups of abstract fields; and (iii) absolute Galois groups of local and global fields. Comment: submitted for proceedings of the International Colloquium on Arithmetic Geometry held at TIFR, Mumbai in January 2020. In this version the results on liftable finite groups are improved due to a remark of Ali Cheraghi
