We prove uniform continuity of radially symmetric vector minimizers to multiple integrals on a ball , among the Sobolev functions in , using a jointly convex lsc with even and superlinear. Besides such basic hypotheses, is assumed to satisfy also a geometrical constraint, which we call quasi - scalar; the simplest example being the biradial case . Complete liberty is given for to take the value, so that our minimization problem implicitly also represents e.g. distributed-parameter optimal control problems, on constrained domains, under PDEs or inclusions in explicit or implicit form. While generic radial functions in this Sobolev space oscillate wildly as , our minimizing profile-curve is, in contrast, absolutely continuous and tame, in the sense that its “static level” always increases with , a original feature of our result.
