Popis: The paper generalizes the method of Zhao for an infinite family of Q -curves and establishes some analytic results on the 2-part of the Birch and Swinnerton-Dyer conjecture. We give lower bounds on the 2-adic valuations of the algebraic part of the L-values at s = 1 for those Q -curves. Moreover, we also discuss 2-descent on Q -curves and compute their Mordell-Weil group and Tate-Shafarevich group.
