Abstract: Let X be a projective curve over $${\mathbb Q}$$Q and $${t\in {\mathbb Q}(X)}$$t∈Q(X) a non-constant rational function of degree $${n\ge 2}$$n≥2. For every $${\tau \in {\mathbb Z}}$$τ∈Z pick $${P_\tau \in X(\bar{\mathbb Q})}$$Pτ∈X(Q¯) such that $${t(P_\tau… read more here.

DOI: 10.1007/s10474-017-0770-y
Abstract: For an algebraic number α, the metric Mahler measure $${m_1(\alpha)}$$m1(α) was first studied by Dubickas and Smyth [4] and was later generalized to the t-metric Mahler measure $${m_t(\alpha)}$$mt(α) by the author [16]. The definition of… read more here.

DOI: 10.1016/j.jnt.2018.04.008
Abstract: Abstract We obtain a Voronoi–Oppenheim summation formula for divisor functions of totally real number fields. This generalizes a formula proved by Oppenheim in 1927. We use a similar method to the one developed by Beineke… read more here.

Abstract: Abstract We consider pro-p-extensions of a number field in which the ramification and decomposition are restricted over an intermediate Z p -extension. For such a maximal pro-p-extension under a certain restriction condition, we obtain a… read more here.
