Equivariant primitive harmonic maps into $k-$symmetric spaces, with applications to Willmore surfaces

In this note we discuss the construction of equivariant primitive harmonic maps into $k-$symmetric spaces and give many applications to the construction of Willmore surfaces. In particular, examples of $S^1-$equivariant Willmore Moebius strips in $S^3$ are obtained as generalizations of the Lawson minimal Klein Bottles in $S^3$.
