In the present study, we deal with canal hypersurfaces according to extended
Darboux frame field of second kind in Euclidean 4-space (E4) and in this
context, firstly we obtain the Gaussian, mean and principal curvatures of
the canal hypersurface according to extended Darboux frame field of second
kind and give some results for flatness and minimality of these
hypersurfaces in E4. Also, we give some results for Weingarten canal
hypersurfaces according to extended Darboux frame field of second kind in E4
and finally, we construct an example.
