On uniform lower bound of the Galois images associated to elliptic curves

Let p be a prime and let K be a number field. Let ρ E , p : G K Aut ( T p E ) GL 2 ( p ) be the Galois representation given by the Galois action on the p -adic Tate module of an elliptic curve E over K . Serre showed that the image of ρ E , p is open if E has no complex multiplication. For an elliptic curve E over K whose j -invariant does not appear in an exceptional finite set (which is non-explicit however), we give an explicit uniform lower bound of the size of the image of ρ E , p .
