摘要

Hilbert Problem 15 required an understanding of Schubert's book[1],both its methods and its results.In this paper,following his idea,we prove that the formulas in§6,§7,§10,about the incidence of points,lines and planes,are all correct.As an application,we prove formulas 8 and 9 in §12,which are frequently used in his book.
