论文摘要
我们考虑在(i)有限组的表示设置中将mod p表示为mod p^2表示; (ii)抽象领域的绝对Galois组; (iii)本地和全球领域的绝对Galois组。
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.
