    't Hooft-Polyakov monopole of higher generalized angular momenta

    Full text link
    We recall the quaternionic fomulation, which can simplify the computation of the linearized Yang-Mills-Higgs equation in the background of a 't Hooft-Polyakov monopole. We then study the solutions in the cases j=0j=0, j=1j=1 and j2j\geq 2 separately. In particular, we investigate the spectral properties of the monopoles. We focus on some of the bound states and show that as the generalized momentum increases, the kk-th eigenvalue tends to 1. We show the existence of Feshbach resonance for \om <1 in the coupled system and calculated the partial cross section when \om >1.Comment: 20 pages, 3 figures and 4 table

    Akashi series, characteristic elements and congruence of Galois representations

    Full text link
    In this paper, we compare the Akashi series of the Pontryagin dual of the Selmer groups of two Galois representations over a strongly admissible p-adic Lie extension. Namely, we show that whenever the two Galois representations in question are congruent to each other, the Akashi series of one is a unit if and only if the Akashi series of the other is also a unit. We will also obtain similar results for the Euler characteristics of the Selmer groups and the characteristic elements attached to the Selmer groups.Comment: 19 pages. Final versio
