2 results for Willmore-stability

For every   b>1  \;b>1\; fixed, we explicitly construct 11-dimensional families of embedded constrained Willmore tori parametrized by their conformal class   (a,b)\;(a,b)\; with   ab0+  \; a \sim_b 0^+\; deforming the homogenous torus \;fbf^b of conformal class \;(0,b).(0,b). The variational vector field at fbf^b is hereby given by a non…
