Abstract: | Let M be a two-dimensional motive which is pure of weight w over a number field K and let (![phgr](/content/fkq64f2ah108ga7v/xxlarge966.gif) : GK Aut(H (M) )) be the system of the -adic realizations. Choose GK-invariant ![Zopf](/content/fkq64f2ah108ga7v/xxlarge8484.gif) -lattices T of H (M) and let (![phgr](/content/fkq64f2ah108ga7v/xxlarge966.gif) :GK GL (T )) be the corresponding system of integral representations. Then either for almost all primes ![phgr](/content/fkq64f2ah108ga7v/xxlarge966.gif) (GK) consist of all the elements of GL(T ) with determinant in (![Zopf](/content/fkq64f2ah108ga7v/xxlarge8484.gif) *)–w or the system (![phgr](/content/fkq64f2ah108ga7v/xxlarge966.gif) ) is associated to algebraic Hecke characters. We also can prove an adelic version of our results.Mathematics Subject Classification (2000): 11F80 |
