Generating a Type of Concave Cupolae of Fourth Sort

The paper discusses the generation of a specific group of polyhedra, Concave Cupolae of Fourth Sort (CC IV) with regular polygonal bases, using constructive and analytical procedures. Beside determination of the parameters of these polyhedra, the paper deals with their visualization, by the application of graphical software MATLAB. We consider one of the four possible types of forming the lateral surfaces of the Concave Cupolae of fourth sort.https://www.ct.upt.ro/buletinhidro/issue_2013_1.htm https://www.ct.upt.ro/buletinhidro/2013-1/018%20Misik%20Generating_corrected.pd
