(數論天使系列叢書)The Iwasawa µ-Invariant of p-Adic Hecke L-Functions[岩澤µ-不變數與p-進赫克代數]

For an odd prime p, we compute the μ-invariant of the anticyclotomic Katz p-adic L-function of a p-ordinary CM field if the conductor of the branch character is a product of primes split over the maximal real subfield. Except for rare cases where the root number of the p-adic functional equation is congruent to −1 modulo p, the invariant vanishes.
