COMPUTATION OF NIELSEN NUMBERS FOR CERTAIN MAPS OF HYPERBOLIC SURFACES
김승원 충청수학회 2015 충청수학회지 Vol.28 No.2
Let X be a closed surface for which the Euler charac- teristic (X) is negative, and let f : X ! X be a self-map that is not surjective. In this short paper, we prove that we can compute the Nielsen number of f, N(f), under some algebraic conditions.
