Uçum, Ali; Erdem, Hatice Altin; İlarslan, Kazım Inextensible flows of partially null and pseudo null curves in semi-Euclidean 4-space with index 2. (English) Zbl 1474.53262 Novi Sad J. Math. 46, No. 1, 115-129 (2016). Summary: In this paper, we consider the inextensible flows in semi-Euclidean 4-space with index \(2 (\mathbb E^4_2)\). We give the necessary and sufficient conditions for the flow to be inextensible and we find the evolution equations for the inextensible flows in semi-Euclidean 4-space with index \(2 (\mathbb E^4_2)\).
