英文摘要
We studied Galois covers, in particular, double covers of algebraic surfaces from a view point of number theory, and applied our result to study topology of open algebraic surfaces. We studied splitting curves in double covers, number theory of elliptic curves over the rational function field of one variable and their application to explicit construction problem for Galois covers. Based on our results, we gave examples of Zariski pairs for conic-line arrangements and Zariski N-plets for conic arrangements.
