Tate twist
For example , if "K" is a field , "GK" is its absolute Galois group , and ρ : "GK" → AutQ"p" ( "V" ) is a representation of "GK" on a finite-dimensional vector space "V" over the field Q"p" of "p"-adic numbers , then the Tate twist of "V" , denoted "V" ( 1 ) , is the representation on the tensor product "V"⊗Q"p" ( 1 ) , where Q"p" ( 1 ) is the "p"-adic cyclotomic character ( i . e .
