Continuity of generalized wave maps on the sphere. (English) Zbl 1389.35230

Summary: We consider a generalization of wave maps based on the Adkins-Nappi model of nuclear physics. In particular, we show that solutions to this equation remain continuous at the origin, which is a first step towards establishing a regularity theory for this equation.
