Abstract:
Let n be a prime, A, B, C disjoint sets, $f:{Z_n} \to A \cup B \cup C$ be such that $f(\bar x) \in A$ iff $f( - \bar x) \in C$ and $f(\bar x + \bar y) \notin C$ whenever $f(\bar x),f(\bar y) \in A$. Then the cardinality of ${f^{ - 1}}[B]$ tends to infinity with n. Using this, certain eigenvalues for automorphisms of the Riemann surfaces defined by the equation ${y^n} = {x^{{m_1}}}{(x - 1)^{{m_2}}}{(x - z)^{{m_3}}}$ are counted.References
