“…Such an approach using the angle function has been used for instance in [20] to prove well-posedness and global existence for a flow towards elastica. Local and global existence of solutions for the classical elastic flow, given by a parabolic fourth order equation in R n , has been shown in several works, for instance [10,16,8,7,15,21,6,19,17,18]. For a more detailed overview, see the recent survey [14].…”
