Canal Hypersurfaces Generated by Non-Null Curves in Lorentz-Minkowski 4-Space

In the present paper, firstly we obtain the general expression of the canal hypersurfaces which are formed as the envelope of a family of pseudo hyperspheres, pseudo hyperbolic hyperspheres and null hypercones in $E_1^4$ and give their some geometric invariants such as unit normal vector fields, Gaussian curvatures, mean curvatures and principal curvatures. Also we give some results about their flatness and minimality conditions and Weingarten canal hypersurfaces. Also, we obtain these characterizations for tubular hypersurfaces in $E_1^4$ by taking constant radius function and finally we construct some examples and visualize them with the aid of Mathematica.
