Gamma-convergence results for phase-field approximations of the 2D-Euler Elastica Functional
Luca Mugnai
We establish some new results about the -limit, with respect to the -topology, of two different (but related) phase-field approximations of the so-called Euler's Elastica B…

Confined elastic curves
Patrick W. Dondl, Luca Mugnai, Matthias Röger
We consider the problem of minimizing Euler's elastica energy for simple closed curves confined to the unit disk. We approximate a simple closed curve by the zero level set of a fu…
