Abstract

We investigate the problem of -loops, namely closed curves in the three-dimensional Euclidean space, with prescribed curvature and torsion . In particular we focus on some perturbative cases, taking and with and converging to the constants 1 and 0, respectively, as . We prove existence of branches of -loops (for small ) emanating from circles which correspond to stable zeroes of a suitable vector field .
