Abstract:
Among planar curves, the $p$-bending energy is defined by the $L^p$-norm of the signed curvature, and critical points of the $p$-bending energy under the fixed length constraint are called $p$-elasticae. The aim of this talk is to give a complete classification of planar $p$-elasticae. A key point is to introduce a new type of generalization of the Jacobi elliptic functions, which also leads us to optimal regularity of planar $p$-elasticae. This talk is based on a joint work with Prof. Tatsuya Miura (Tokyo Institute of Technology), and its arXiv identifier is2203.08535.
