On some properties of normally-inflective complexes with simple inflective center in $$$E_3$$$

Ye.N. Ishchenko (Dnipropetrovsk State University)


In the paper, we consider the special degenerate class of mormally-inflective complexes with simple inflective center in three-dimensional Euclidean space $$$E_3$$$. We prove that to construct this class of complexes one should take an arbitrary curve and draw sheaf of straight lines through each point of this curve. For arbitrary normally-inflective complex with simple inflective center we establish that such complex is fibered into two one-parametric families of congruences.
