Abstract
This paper studies Iwasawa invariants in anti-cyclotomic towers. We do this by proposing two heuristics supported by computations. First we propose the Intersection Heuristics: these model “how often” the p-Hilbert class field of an imaginary quadratic field intersects the anti-cyclotomic tower and to what extent. Second we propose the Invariants Heuristics: these predict that the Iwasawa invariants and usually vanish for imaginary quadratic fields where p is non-split.

反分圆 ℤp-扩展的启发式方法
摘要
本文研究了反分圆塔中的 Iwasawa 不变量。我们通过提出两种由计算支持的启发式方法来做到这一点。首先,我们提出相交启发法:这些模型模拟了虚二次场的p-希尔伯特类场与反分圆塔相交的“频率”以及相交的程度。其次,我们提出不变量启发式:这些预测 Iwasawa 不变量和对于p不可分裂的虚二次场,通常消失。
