Estimating Nielsen Numbers on Wedge Product Spaces

Open Access
Research Article


Let Open image in new window be a self-map of a finite polyhedron that is an aspherical wedge product space Open image in new window . In this paper, we estimate the Nielsen number Open image in new window of Open image in new window . In particular, we study some algebraic properties of the free products and then estimate Nielsen numbers on torus wedge surface with boundary, Klein bottle wedge surface with boundary, and torus wedge torus.
