碩士 === 國立中正大學 === 數學研究所 === 91 === In the first part of this thesis, we list and prove some theorems of commutative rings and graded commutative rings. In the second part, we give the definition of sheaves and introduce two functors; f^{-1} and f_*, and the duality of the two functors. In the third part of this thesis, we define and discuss projective schemes and their morphisms, and list and prove some theorems about them.
