Abstract
Let p≥5 be a prime If an irreducible component of the spectrum of the ‘big’ ordinary Hecke algebra does not have complex multiplication under mild assumptions we prove that the image of its mod p Galois representation contains an open subgroup of Open image in new window for the canonical “weight” variable T This fact appears to be deep as it is almost equivalent to the vanishing of the μinvariant of the Kubota–Leopoldt padic Lfunction and the anticyclotomic Katz padic Lfunction Another key ingredient of the proof is the anticyclotomic main conjecture proven by Rubin/Mazur–TilouineThe author is partially supported by the NSF grant DMS 0753991 and DMS 0854949 and part of this work was done during the author’s stay in January to March 2010 at the Institut Henri Poincaré—Centre Emile Borel The author thanks this institution for hospitality and support
