Lancret Helices in \(\mathbb {S}^3\) and \(\mathbb {H}^3\)
摘要
In Chap. 1 a detailed study of Lancret helices in \(\mathbb {R}^3\) was made. As such curves do not close, it was plain that we have to resort to new ambient spaces to give mathematical support to the different models of closed Lancret helices we find in Nature, such as protein chains.
