Main Structure Theorems,d cones. We also prove here existence theorems for some varieties with degenerate Gauss maps, for example, for twisted cones in P. and A. (Theorems 4.12 and 4.14) and establish a structure of twisted cones in ?. (Theorems 4.13). This structure allows us to find a procedure for construction of twiste

In Section 5.3, we consider smooth lines on projective planes over the complete matrix algebra M of order two, the algebra ? of complex numbers, the algebra ?. of double numbers, and the algebra ?. of dual numbers. For the algebras ?, ?., and ?., in the space ??., to these smooth lines ther

By means of these methods, the authors discover the structure of varieties with degenerate Gauss maps, determine the singular points and singular varieties, find focal images and construct a classificati
